RM or non RM
I believe that plays a bigger part of the equation. Not that an RM can go into the NFL and contribute, I just believe it is more difficult to do that, considering the age factor. Look at Paul Lasike, an RM that is trying to see if he can make it as a FB. Will work out on Pro Day sometime in March at BYU, but hope he makes it.
I also will be curious to see how the new conditioning program assists BYU players as they look at giving the NFL a shot. If the new program will decrease injury, increase flexibility and increase more playing time with a better result in health, wonder if the NFL influx will increase. Would be interesting to see those data points.
