after watching highlight videos of reed and ayers, i vote ayers, and it's not even close.
reed's "highlights" are all either him not being blocked or a broken play on offense. he's not doing anything impressive to get to the qb. just right place, right time.
but ayers looks great. he's constantly beating OL much bigger than him with spin, bullrush, you name it. he's using his speed to get around the OL. he appears to have great vision. i'm sold.
