Justin, where'd u play college football? Not michigan, I hope!!!
Also, why didn't you to go to the nfl?
The NFL wasn't in the cards.  I had a very good run for my situation. 
I was a two time Division III All-American.  In 2001, I was the pre-season defensive national MVP.  
I tested out well at the combines.  
I benched 225lbs 40 times, had a 36" vertical, and ran around 4.7 in the 40.  My times and skills were "pro caliber" as a defensive end (which is what I was), but in the end, at 5'10," there were 10,000 other guys with AT LEAST as good of skills who were 6'5".  
I had a great time at the combines though.  It was at Ohio State's indoor facility.  It was just amazing to see the speed of some of the faster guys.  Totally unreal.  
a 4.5 guy will beat a 4.7 guy by 10 yards in the 40.....there were a few 4.3 guys there.  The speed difference at that level is unbelievable.  Those guys were beating FAST players by 15 yards in the 40.  
The top guys get private try-outs, so for the most part, it was just us dreamers hoping to turn in a freak performance to get noticed.
