so as of now I would give return duties to Austun and maybe PR as well or I would consider Ronnie Bell who from the combine and pro day has from an rnd 6 to rnd 4, great hands blocking, blocking and sure hands 4.5 speed but plays faster kinda like Ward, the 80 yd td in 04 vs the pats and the 1 shoe td vs the falcons, this kid will find ways to get open.
Bell did return punts for UM and is shifty. I see him as a perfect 3-4 to rotate with Austin in the middle, as of now you have Austin Muth and Heward as the slot guys
