WCO aside the Washington Redskins will play old style Redskin ball…RUN! Two top flight backs in Portis and Betts.
The passing game is a little behind but from an article on The Offficial site of the Washington Redskins Gary Fitzgerald quoted Zorn:

With Kelly unlikely to play in Thursday’s regular season opener against the New York Giants, the Redskins are expected to dress just four wide receivers: Randle El, Santana Moss, James Thrash and Thomas.
On Sunday, Zorn said the presence of tight end Chris Cooley gives him more options in the passing game.
Cooley can line up as a wide receiver in some sets, Zorn said.
"When you don’t have a wide receiver available to you, the tight end becomes more prominent," Zorn said. "We’re carrying three tight ends on the roster. That’s part of carrying Cooley into a game and allowing him to be a receiver as well as a blocker.

"

no doubt, which is especially frustrating since we devoted two first-day draft picks just to make sure we wouldn’t be… precisely where we are.

lining up with cooley or davis in the slot is the same as running a 3 wr set. we know cooley is as capable of lining up there as any wr, as for davis, maybe maybe not. it is strange to only have kept 5 wrs on the roster, but it probably had something to do with the fact that we kept 3 tes, 2 of whom are almost strictly pass catchers

Your not alone, everyone I spoke with is afraid the Skins offense is hurtin…Campbell is taking way too much time and can’t find his rhythem…the O-line has not showed up the last two preseason games…let’s hope this is just a flook and the real Skins show up on Thursday night.
Smitty’s

and the sad thing is that even if we had somehow traded for Ocho Cinco in the off-season (the favorite rumor of the intertubes), we’d be dealing with an injured wide receiver anyways.
