I would start Garcia. He'll step it up against the Broncos this week. Matthews will have a tough time in Philly. I know why you're having a tough time deciding. It's better to stick with the Fantasy vet than to go with the one week wonder. It doesn't always work out, but the vet will do better 70% of the time. The other 30% were breakout performances, and that's hard to tell. Arizona's D is terrible.
garcia looked terrible in game 1. He really needs to get his game back. They may resort to the runing game more often than ever if Owens and Stokes are gonna get covered like the Giants did. Eric Johnson is a good sleeper pick here, garcia prefers johnson over jj stokes so ej will have a good year.
