Yeah, our STs stunk even with arguably one of the best gunners in the league so somehow I tend to doubt that Boobie was anything of a difference maker in that regard. I think everyone agrees he couldnt hold Fred's jock as a running back. And with respect to age, STs is where you want a younger player who can work on being a useful backup and maybe someday a starter, not exactly something you could hope for from Boobie. Seems like more a Doug Whaley defence argument than a football one.
With respect to Gillislee, who I think is a good find, I wonder if he could be serviceable as a return man for kickoffs and maybe for punts. He has excellent vision and a decent burst even if not a real burner.
