I agree that Mann is very athletic, however with this being agreed on, I beleive the McNairy coach uses him the way he needs him. If it calls for being inside, I beleive that is where he will be. The coach no mater who he is sees his players everyday in practice. He knows their strengths and weaknesses. You could look at every team and you would change some players around on every one of them.
Another thing, when you post someone up for the purpose of going one on one, the others just stand around and watch.
Just my opinion.
