00:00:00.000 --> 00:00:05.000
- This concept video is answering the member question.

2
00:00:05.000 --> 00:00:12.100
What's the difference between owner deviation and a cast?

3
00:00:12.100 --> 00:00:15.860
So I have a few videos on the arm movements

4
00:00:15.860 --> 00:00:18.140
during the downswing and videos on the cast,

5
00:00:18.140 --> 00:00:21.140
but wanted to answer this member's question

6
00:00:21.140 --> 00:00:24.580
about what's the difference between owner deviation

7
00:00:24.580 --> 00:00:27.540
and a cast because we are often see on video

8
00:00:27.540 --> 00:00:29.460
and we're often told that anything

9
00:00:29.460 --> 00:00:32.800
that looks like this is a casting motion.

10
00:00:32.800 --> 00:00:36.420
I've released my energy and then it's usually gonna be

11
00:00:36.420 --> 00:00:39.420
kind of too wide, too early and then breaking down

12
00:00:39.420 --> 00:00:43.980
during the release, but we've heard lots of good golfers

13
00:00:43.980 --> 00:00:46.020
and a lot of coaches advocate getting

14
00:00:46.020 --> 00:00:48.780
into this owner deviation early.

15
00:00:48.780 --> 00:00:51.340
So let's reconcile the two.

16
00:00:51.340 --> 00:00:54.300
So we're gonna use a downswing checkpoint

17
00:00:54.300 --> 00:00:57.420
as our reference for a cast versus leg

18
00:00:57.420 --> 00:00:59.340
and then we'll talk through the mechanics of it.

19
00:00:59.340 --> 00:01:02.260
So the downswing leg checkpoint is basically looking

20
00:01:02.260 --> 00:01:06.220
at when we're about club parallel to the ground,

21
00:01:06.220 --> 00:01:07.380
where's the butt end of the club

22
00:01:07.380 --> 00:01:09.820
in relationship to the golf ball.

23
00:01:09.820 --> 00:01:12.700
When you do a cast, what typically happens

24
00:01:12.700 --> 00:01:14.380
is we go up to the top of the swing

25
00:01:14.380 --> 00:01:18.620
and then I throw the club head out away from me.

26
00:01:18.620 --> 00:01:22.540
Now that has long been described as more of an unhinged

27
00:01:22.540 --> 00:01:25.940
or yeah, an owner deviation or an unhinged movement,

28
00:01:25.940 --> 00:01:28.660
but what I've seen on 3D is it's more

29
00:01:28.660 --> 00:01:30.780
of a straightening of the trail arm

30
00:01:30.780 --> 00:01:33.740
and a flexing of the trail wrist,

31
00:01:33.740 --> 00:01:36.260
or potentially it could be a pulling

32
00:01:36.260 --> 00:01:39.660
of the lead shoulder kind of going like this,

33
00:01:39.660 --> 00:01:43.300
which throws that club head out there,

34
00:01:43.300 --> 00:01:46.500
releasing the angular energy a little bit too soon

35
00:01:46.500 --> 00:01:48.220
and then it tends to kind of slow down

36
00:01:48.220 --> 00:01:50.020
or coast on the way through.

37
00:01:50.020 --> 00:01:56.060
But if I was to kind of separate the cast

38
00:01:56.060 --> 00:01:57.660
from the owner deviation,

39
00:01:57.660 --> 00:02:00.220
let's walk through the owner deviation first.

40
00:02:00.220 --> 00:02:02.580
So if I get up here and I owner deviate,

41
00:02:02.580 --> 00:02:05.180
that looks like I've casted the club.

42
00:02:05.180 --> 00:02:09.580
But if now, if I was to rotate my body

43
00:02:09.580 --> 00:02:12.620
and let my arms get into a good delivery position,

44
00:02:12.620 --> 00:02:16.420
you can see from here that I'm no longer in a position

45
00:02:16.420 --> 00:02:19.020
that looks like I've casted it.

46
00:02:19.020 --> 00:02:22.020
I've maintained the leg because I maintain the bend

47
00:02:22.020 --> 00:02:24.420
in my elbow and the bend in my wrist.

48
00:02:26.140 --> 00:02:29.380
So this motion of unhinging,

49
00:02:29.380 --> 00:02:32.580
if I then add the extension of the wrist,

50
00:02:32.580 --> 00:02:35.900
add the bend of the elbow and then add the turn of the body,

51
00:02:35.900 --> 00:02:38.020
it no longer looks like a cast.

52
00:02:38.020 --> 00:02:41.100
What makes this look like a cast

53
00:02:41.100 --> 00:02:44.620
is the combination of the arms moving too soon

54
00:02:44.620 --> 00:02:47.660
and the body not really driving in transition.

55
00:02:47.660 --> 00:02:51.700
So the goal in this sequencing is to get the lower body

56
00:02:51.700 --> 00:02:52.940
in the core to lead.

57
00:02:52.940 --> 00:02:55.300
That helps get the arms in front,

58
00:02:55.300 --> 00:02:58.980
getting into this good kind of narrow delivery position.

59
00:02:58.980 --> 00:03:01.220
And then I'm going to shallow the club

60
00:03:01.220 --> 00:03:05.180
by getting some of the width from this owner deviation.

61
00:03:05.180 --> 00:03:10.100
But as long as I maintain the wrist angles appropriately,

62
00:03:10.100 --> 00:03:13.820
then it's not a cast because I've still led with my body

63
00:03:13.820 --> 00:03:17.860
and I've still maintained some of the spring

64
00:03:17.860 --> 00:03:20.260
or some of the stored energy in my wrist

65
00:03:20.260 --> 00:03:22.260
that I can release down at the bottom.

66
00:03:22.260 --> 00:03:27.180
So it can be tricky, especially if you grew up

67
00:03:27.180 --> 00:03:30.140
taking golf lessons in kind of the 80s or 90s

68
00:03:30.140 --> 00:03:33.940
where casting was really discouraged.

69
00:03:33.940 --> 00:03:36.180
It can be a little bit tricky,

70
00:03:36.180 --> 00:03:38.100
but I think 3D has helped us understand

71
00:03:38.100 --> 00:03:41.500
a little bit better detail really what's happening

72
00:03:41.500 --> 00:03:45.500
at the wrist and how you can create the different looks.

73
00:03:45.500 --> 00:03:48.900
I don't want you to look like you're casting it way out there,

74
00:03:48.900 --> 00:03:52.780
but a lot of golfers kind of hold onto this angle

75
00:03:52.780 --> 00:03:54.980
of the wrist too long.

76
00:03:54.980 --> 00:03:57.020
Instead of getting that owner deviation

77
00:03:57.020 --> 00:03:58.340
at the appropriate time,

78
00:03:58.340 --> 00:04:01.500
I think that you have to be able to separate

79
00:04:01.500 --> 00:04:05.380
width and the release from casting

80
00:04:05.380 --> 00:04:08.980
and more of a sequence or more of a throw pattern

81
00:04:08.980 --> 00:04:09.820
from the yard.

82
00:04:09.820 --> 00:04:13.780
So let's do a little demo here.

83
00:04:13.780 --> 00:04:15.980
If I was to do more of a casting pattern,

84
00:04:15.980 --> 00:04:18.180
it would look a get up to the top of the swing

85
00:04:18.180 --> 00:04:21.700
and then I would straighten that right arm and wrist

86
00:04:21.700 --> 00:04:26.620
very early and it would get wide

87
00:04:26.620 --> 00:04:28.700
and then kind of narrow on the way through

88
00:04:28.700 --> 00:04:30.340
and my body wouldn't do a whole lot.

89
00:04:30.340 --> 00:04:34.100
Now if I was to emphasize the owner deviation,

90
00:04:34.100 --> 00:04:39.100
but still getting into a good bracing and body sequencing,

91
00:04:39.100 --> 00:04:46.620
then it will probably still have a look

92
00:04:46.620 --> 00:04:48.740
of a good downswing lag.

93
00:04:48.740 --> 00:04:51.940
Even though I was shallowing the club with the wrist,

94
00:04:51.940 --> 00:04:56.940
I maintained the lag or the energy in the wrist

95
00:04:56.940 --> 00:05:00.500
holding the club back, not so much holding it up.

96
00:05:00.500 --> 00:05:02.300
I think that's one of the hallmarks

97
00:05:02.300 --> 00:05:03.700
or distinguishing characteristics

98
00:05:03.700 --> 00:05:05.660
between owner deviation and the cast.
