I watched Jake Locker's interview with Mike Mayock and the NFL Network crew tonight (February 24th). Mayock mentioned that he noticed that Locker was (paraphrasing and injecting some football terminology) coming to a skinny base and then over-striding into throws. Locker mentioned that Mayock was correct, and Locker also mentioned that he thought he wasn't transitioning his weight from his back foot to his front foot properly. I re-watched the USC cut (linked), Oregon State, BYU, and Arizona. I noticed what Mayock and Locker were talking about, but it's not as prevelent as I thought.... which made me feel better, since I hadn't noticed it. Locker does come to a skinny base and overstride, but he's not doing it enough to make it super noticeable. What I did notice was that Locker almost never transitions his weight to his front foot. He also steps a bit to his left, and is very inconsistent in pointing his front foot at the target. I also noticed that Locker only did this in the pocket from a base. When he rolled out, he was consistently good in his weight transition, and his foot pointing. What's all this mean? Check Locker's tape. He's got ninja-like accuracy on the move. He's moving, so the weight transition comes naturally, as he's running. When he's in the pocket, it's not there. What does weight transition effect? Accuracy. Especially vertical accuracy, in terms of hitting the strike zone up and down. What do we see? Locker missing high all the time. I think I've finally come to terms (at least to me) on why Locker is missing the strike zone.
