Is Darren a specialty player or a down to down player? I don't know. I agree they are there, but they normally don't have long careers. One exception of a position player that I saw play in college quite a bit is Dat Nguyen the linebacker for Dallas. I think he was less than 240, which for a linebacker is small. I also had a teammate in high school who was 5' 4" and weighed 160, as a nose guard that Don Shula said was the toughest high school player he ever saw play. He had a heck of a heart but just didn't have the size. Unfortunately, he couldn't even make a college team and ended up playing baseball a game he was more suited for. I think that is a part of it as well, there are certain sizes that are better for certain sports. I was originally recruited as a tight end for example, but now a 5'11" 180-pound tight end is excessively small, even for most small college programs. Curtis gives a good name but it would be interesting to do a search of various college level programs, and pro level programs and see how many position players (they take the down to down beating) there are that are playing that are small in stature. I’ll give credit to the little guys though, to be playing football, they may be little in stature but awful big at heart.

I did just find this. The average NFL player is 6'1.5" and 245 lbs
