What I read as to what the staff wants:
Power regardless of the difference a few pounds might make. And agility and striking ability, to buffoon the opponents' O-Lines, penetrate gaps and change the line-of-scrimmage [not just stone-wall it], and the Gorilla-factor of being able to "get-after-it" once released from the [blocking] cage. "Buddha" is OK, as the Staff sees the future, only if he can violently manipulate the area and then run.
The pros offer a different NT situation than does college because they face extreme hugeness all day long which is accompanied in those O-Linemen with extreme power. In college it is not that daunting all day long, plus your number two NT may well be able to spell number one with very little drop-off of ability. That is rarely true in the pros, where outstanding NTs are rare.
