College football is full of players who are stars at their respective positions but are considered 'tweeners at the next level. They might lack the height or bulk to play their collegiate position in the NFL, or perhaps they have a particular deficiency that will necessitate a position change.
Here's a look at five current prospects who will likely be moving to a different spot on the field when they enter the NFL:
1. Larry English, DE, Northern Illinois
English's strong showing as a senior has done wonders for his NFL draft stock. Scouts know he can rush the passer off the edge thanks to his 31.5 career sacks to date, but the next step towards landing a spot on Day 1 of the draft is to prove he's fluid enough to make the switch from college defensive end to NFL linebacker -- either on the outside in a 3-4 alignment or on the strong side in a 4-3 defense. Needless to say, scouts and coaches will be watching closely when English performs linebacker drills during postseason workouts and all-star games.
