Lock is large (6-foot-3, 223 lbs), has a strong arm and sportiness, but it was contradictory when toasting and moving Tuesday. It was similar to what you see of him on tape. He really needs to be more consistent with his trajectory of touch throw and deeper passes. An important topic of conversation of the day was his 9-inch hands weighing. It was quite surprising and obviously a problem when it comes to ball safety, pump counterfeiting and dealing with bad weather. – McShay
Crew: South | Uniform number: 7 | QB Ranking: 4
Grier looked pretty good when he dropped out of the middle on Tuesday. It's all new to him, but he seemed mostly comfortable and showed fast feet. I felt he was crucial in passing when his first reading provided the answer, but he still tends to temporarily hold onto his primary goal for too long. He showed a stronger arm than expected, but was a little inconsistent when he threw on the move and was out of the game. – McShay
