I don't like it. Return men don't get hurt as frequently as some might believe, but they do get hurt. Suddenly we are not much deeper at WR than we are at DB and if we are going to put anyone at risk, I don't think it should be our #1 and (possibly) #2 WRs. Especially since neither has performed such duties with great regularity. And no way, no how should we ever consider Sherm for PRs. That's madness, imo.
It really is amazing to me that we are even in this predicament. Michael (for example) is still so far behind, and apparently still so untrustworthy, that he can't return a kick-off? My gawd, Pete. Fire someone. Anyone.
