There is more to punt returning than catch and run. Mark Jones is the last good punt returner I can remember(2003). Devrin is the only good punt returner we have had since that time. However, I am not a fan of Devrin playing RB. I hope he takes Zach's spot in the slot next year and we have Neal, Lane and Green. That is a formidable trio , no matter who is playing QB.
i like to think of zach as the football teams version of dane bradshaw. hes not the most physically gifted guy out there but by grit and determination he gets the job done and is a good lead by example and hustle type player. also seems to be a great kid and i hope he gets on with an nfl club. i doubt hes drafted unless he posts some insane combine stats but hopefully he at least makes it on a squad and gets a chance to perform at the next level.
