Are Robiskie and Hartline really as good as most pundits say they are?

I despise Ohio State, but I think that their wideouts are good college players (Hartline and Robiskie). The Michigan comparisons that we be most apt seem to me to be Marcus Knight and Jason Avant, and I simply cannot believe that either one of them is a game changer like Terry Glenn was. I find it hard to believe that Robiskie is really a first-team, All-Big Ten choice, which I thought I saw in one poll. Both of these guys are probably #3 or 4 possession receivers at best at the next level. What do you think?
