Players whose adjustment from playing in or against the spread offense could be major factors in where they are selected in the NFL draft:
Paxton Lynch, QB, Memphis: Taking a snap at the line will be something very new for Lynch, as will reading defenses while dropping back.
Dak Prescott, QB, Mississippi State: Great athlete in type of offense rarely run in pros, must show he has pocket presence for NFL passing game.
Kenneth Dixon, RB, Louisiana Tech: Tremendously productive player in Bulldogs' spread who can run and catch. But can he pick up blitzes and pass protect in general?
Austin Hooper, TE, Stanford: Avoided spread, comes from pro-style attack that translates well to NFL. That earns all Stanford tight ends brownie points with scouts.
Laremy Tunsil, OT, Mississippi: Presumptive top overall pick before Rams and Eagles traded up for QBs. Tunsil, who missed part of 2015 for NCAA infraction, must show he handle three-point stance and footwork with consistency.
Germain Ifedi, OT, Texas A&M: Among most versatile linemen in this crop, he can play guard as well. But can he learn the blocking fundamentals needed in the NFL power game after not needing them in Aggies' spread?
William Jackson III, CB, Houston: Jackson was outstanding, leading NCAA in passes defensed. That should help his stock because he's seen so much from opposing offenses already.
Terrance Smith, LB, Florida State: Yet another terrific Seminoles athlete at the position, but he's unproven in pass coverage against versatile tight ends because he hasn't seen them.
