Interesting thing about this Alen, Gino Toretta was asked about the difference between NCCA footballs vs NFL footballs and the only difference is..different stripes are painted on the ball.

 

I assumed the College ball was a tad thicker? Looks it anyhow.

 

It's true that the NCAA and NFL footballs are the same regulation. However, there is a tolerance afforded when making the balls. For example, and according to Wilson, the Short Circumference ranges between 20 3/4"- 21 1/4". There are different models and patterns of the Wilson football that fall under these specifications. I believe that the college ranks uses a different model than the NFL and that is built to the smallest specifications and thus makes it easier to throw/control.

 

Remember seeing this somewhere else. Pretty cool.
