“Has he improved footwork-wise, throwing motion, knowledge of coverages, all those things,” O’Brien said Tuesday. “You kind of try to look for similar things even though each player is different so that when you go back at any position and you judge what you’re going to do and you decide what you’re going to do, you at least have a progression of these eight to 10 categories.”
While O’Brien expects players to excel in a scripted workout with familiar receivers, there are some limitations to how much can be really be evaluated.
Referred to as “Johnny Day” by O’Brien, Manziel is expected to throw to five former teammates: wide receivers Mike Evans, Travis Labhart and Derel Walker, tight end Nehemiah Hicks, and running back Ben Malena. Evans will also work out for NFL representatives after not participating in A&M's Pro Day on March 5.
The Heisman Trophy-winning Manziel has been training this offseason in San Diego with his private quarterback coach, George Whitfield, who organized Thursday’s Pro Day.
O’Brien, general manager Rick Smith, and quarterbacks coach George Godsey will attend Manziel’s Pro Day scheduled to begin at 11 a.m. at Texas A&M’s indoor practice facility.
