Redskins quarterback Robert Griffin III said he would be open to the idea of receiving advice on how to improve his sliding. Whether serious or not, Griffin said that he could enlist the services of Nationals outfielder Bryce Harper.

“If Bryce wants to do that, I’m definitely up for that,” Griffin said before pointing to the camera and saying, “Bryce, so, we can do that if you want to.”

Ever since his knee injury, Griffin has heard the importance that he learn how to slide on runs to protect himself from violent hits.

On Sunday, Griffin struggled in that area, taking an awkward seated plop to avoid a hit near the sideline at the end of a third-quarter run, and then fumbling during a head-first dive on a fourth-quarter play that killed a potential scoring drive.

Redskins coach Mike Shanahan said on Monday that Griffin still is learning how to slide, because at Baylor and in high school, the quarterback never had to do so.

Griffin said his struggles in the sliding department are more mental than anything, but that he’s trying to correct those problems.

“The thing of the problem is, I’m not a great slider, should I say?” he said with a grin. “I know how to slide. I don’t know how to baseball slide, and I think that’s what they’re talking about. But there’s just an emphasis on sliding feet-first as opposed to going forward since that rule’s in place. It protects you as a quarterback when you’re going feet-first, so that’s what I’m going to do. I’ve got to make a mental note of that and try to slide feet-first.”

Griffin confessed that he hasn’t practiced sliding since training camp. Asked what that work consisted of he said, “You basically run up to a defender and you slide.”

The quarterback added, “It’s harder [in practice]. It’s easier to slide with football pants on. The slickness of the pants – I know I’m going into detail – but the slickness of the pants helps you slide. But when you have shorts on and stuff like that, it’s less conducive to sliding. But I have.”
