The Eagles used the WR Screen Action 4 times against the Raiders, each time getting slightly different response and resulting in a slightly different play. It's interesting to pay attention to because it gives a sense of the back-and-forth that was occurring as the game was playing out. The first play also may give an indication about what the weekly prep was like and what Tarver's initial scheme was set to prevent.
(1) 42 yd completion to Riley Cooper
Rotating to Cover2 with Sio Moore having the Hook-to-Curl zone. Moore bites hard on the run action (not a particularly good one at that) and vacates his zone, leaving 2 defenders on 3 receivers on the outside (2TEs as blockers, Cooper as the screen WR). Then Riley Cooper shows that he's faster than Tracy Porter
(2) 6 yd Inside Handoff to Shady McCoy w/WR Screen Action
This time the Raiders have man coverage. If Nick Roach didn't already realize it, 4 Raiders are telling him to go cover the TE outside. The Man coverage clears out the middle of the field and sets up the inside handoff to McCoy. Moore takes an outside attack (playing Foles on the Read Option) and gives a lane inside. Burnett avoids (most of) the Eagles' center's block. Moore gets just enough of McCoy's ankle to let Burnett make the play.
(3) 32 yd Inside Handoff to Bryce Brown w/WR Screen Action
Again the WR Screen action clears out the middle of the field. The DL gets destroyed by the Eagles' OL, with Houston getting owned by Jason Peters to the point of screening off Burnett as the outside defender. Inside, Vance Walker gets crushed well to the inside, opening up a gigantic hole. The C will release and get onto Nick Roach. When Brown gets past the first level, Roach being blocked sets up a 2-way go and CWood is stuck in No Man's Land. Brown presses the hole and then cuts to the outside. CWood follows, gets a solid shot on Brown, but with the angle, he can't bring him down or wrap him up. Brown then gives Jenkins a move and hits the outside.
(4) -3 yd HalfBack Screen to Shady McCoy w/Fake WR Screen
Fake the WR Screen to the outside and the turn around for the Halfback screen to the opposite side. Shady has space and blockers, but Burnett reads the play and attacks before the blockers can set up. Also, Sio Moore's pressure and jump forces a high throw that slows things down just enough so that Burnett can get a clean hit before McCoy can set up and prepare to make a move.
