Let's see 772 yards on a mediocre, run first team with an average to below average QB and signing at a cheap price...and people are complaining about signing him?
He is no Galloway, not be a long shot. He is younger, had much better numbers for a longer period of time on worse teams and doing it with little time missed.
He isn't going to burn you down the sidelines but unlike Galloway he will catch it if you throw it to him. He isn't going to be the top dog on the receiver corps, then again he doesn't need to be and he knows that. He just needs to get the balls thrown to him, which is what he is able to do.
His ability to get at balls thrown to him should make up for some of Welker not being there alongside Edelman taking Welker's role in the slot- helping the team in another area that the other receivers aren't able to do or isn't known yet that they can do...
