Several Redskins beat reporters commented about DeSean Jackson’s limited blocking abilities as the Cardinals game was going on last weekend, and the topic came up at Jay Gruden’s Wednesday news conference.

Turns out the topic also came up during Chris Cooley’s weekly film breakdown of the Redskins offense for ESPN 980. Cooley brought up Jackson’s blocking not to criticize the wide receiver, but to criticize the coaching staff for putting the wide receiver in untenable situations.

“Do not allow number 11 to ever be involved in blocking for screens, blocking for bubbles, picking for players in the pass game, [or] run plays to his side of the line of scrimmage,” Cooley said. “He WILL NOT TRY on them. Do not put him in in those situations.”

Wouldn’t that make the Redskins offensive plans easier to diagnose, Cooley was then asked.

“Find another way to break that tendency, but don’t risk losing a play just because you think 11 might try,” Cooley said. “Unless he’s going to say ‘I’ll make a legitimate commitment,’ do not put him in on those plays. It was costly in four or five different situations where plays could have been better.”

An example?

“They throw a bubble screen outside to Andre Roberts,” Cooley said. “[Jackson] doesn’t put his hands on the player, and Roberts takes a no-gain. In the run game, on his side, he will never block anybody. He just won’t. He’s just not going to block anybody. And when Alfred [Morris] breaks something to the second level and the corner’s seven yards off, that’s a seven-yard gain, a six-yard gain, and that looks like nothing. If you have a receiver who’s locked down on the corner, that might be a 20-yard gain. C’mon.”
