but maybe when you say "dual-threat" you're only talking about guys like Michael Vick, who are NFL-capable passers.
Dual Threat i mean anyone who can run and pass on a college level. Vick did both in college but then just ran in NFL. I seem to remember a video based on Ocean's Eleven but with sport convicts and wrongdoers and Vick is suppose to pull the pin of a grenade and throw it, instead he pulls the pin and scrambles. Everyone in the room shouted "Don't scramble throw it!"
Time again the NFL proves that running QB's just can't cut it in the pros, you either have to be a passer who can run or a passer, you can't be a running QB and make it in the pros.
