Pierre Garcon (right) has had one quiet game, one huge game since return (Ricky Carioti/The Washington Post).

Which version of Pierre Garcon will be on display Monday night when the Washington Redskins face the New York Giants at FedEx Field? The version that looked every bit like the Redskins’ top wide receiver during their Thanksgiving triumph in Dallas, with a brilliant play on a 59-yard touchdown catch on his way to a solid all-around performance? Or the diminished version that had only five receiving yards four days earlier in a victory over the Philadelphia Eagles in his return to the lineup after missing four games because of a torn ligament near the second toe of his right foot?

There’s no way to know beforehand, it seems.

“You never know because he’s not 100-percent healthy,” Redskins offensive coordinator Kyle Shanahan said last week. “So when he does feel good and stuff, you guys can see it. I think everyone can see it. He’s a big-time player. That’s what we hope to get. And when he’s not fully going, I still think him out there helps us.”

The issue complicates the Redskins’ game-planning and play-calling.

“It makes me a little less decisive on what we’re going to open up with and stuff we’re going to do because it does change on who we’re trying to get the ball to and stuff like that. [But] it’s definitely a problem I don’t mind having,” Shanahan said. “I’d rather hope to have him than know I’m not going to have him at all.”
