You can't just look at a punter's numbers in college and expect them to translate to the NFL. Often punters in college can get away with bad practices or forms that you can't do at this level. The biggest thing is the snap to kick time. Look at how many colleges have these rugby style punters who take a bunch of steps before kicking. That won't fly against an NFL rush. Even with normal punters, many take an extra step or are just a bit slower than needed for the NFL. Fixing those problems can screw up a punters consistency.
