Strange dude this Ahearn. 2 time NBAD-MVP, hit 110 FTs in a row last year and is a great 3 point shooter. When Kyle Korver and Steve Novak can make great livings being one trick ponys, you should think that Ahearn could do the same.
Novak is 6'8" or 6'9". Korver is 6'7". They can be hidden on D against the weaker offensive players. Ahearn is a PG only and has no chance to guard NBA PG's.
