Best upside: Gage, Clayton or Robinson. WHIR

[GiveUp]

Looking to drop one of my D/ST and take a flier on 1 of these 3.

I start 3 plus a flex and have Boldin, Bowe, DeSean, Percy, Lee Evans and Burleson. I feel I'm set just fine, but I have waiver priority and there are a bunch of owners who grabbed multiple TEs, QBs and D/ST. So I know these guy will probably go.... How has the better upside for the season/trade bait?

Gage has the best #s, but didn't Scaife get hurt and Washington didn't play much right? So the #1 WR on a running team that likes their TEs?
L. Robinson? 10 targets on a suck-hole team playing from behind all season... Sounds like a winner to me for upside!
Or, Mark Clayton? Joe cool looking good and Mason has to turn to dust at some point right? But still a run 1st team.

I like Gage as the solid pick and I can't believe he was dropped (well for bennett so I guess that worked out). But I think Robinson has the most upside.
