Bills' LeSean McCoy on hamstring: Can't really go like I want to

MIAMI GARDENS, Fla. -- After gaining just 16 yards on 11 carries in the Buffalo Bills' 41-14 win Sunday over the Miami Dolphins, running back LeSean McCoy said his lingering hamstring injury is still affecting his performance.

"I was never really effective today like I wanted to be," he said in the locker room after the game. " ... Just trying to go. I can't really go like I want to."

The Bills held McCoy out of last Wednesday's practice and he struggled to get loose early in Sunday's game, riding an exercise bike on the sideline as rookie running back Karlos Williams excelled on the field, gaining 110 yards on 12 carries.

"He's out there sometimes on one-and-a-half legs, but he is unselfish and he's doing a great job picking up blitzes and all that stuff," coach Rex Ryan said after the game. "I feel frustrated for him because I know the kind of mark he wants to put on this team but physically right now he's not quite back to where we need him to be but he's just got to keep going. I love the kid, I love his attitude and he's impressive."

Ryan resisted the idea of sitting McCoy out for the Bills' upcoming game against the New York Giants (1-2).

"Nah, I'll tell you: He's such a weapon" Ryan said. "If we just get him back, if he gets a little bit back -- get a little better, a little better, a little better -- eventually he'll get all the way back. That would be fantastic. But man, it's so hard to do that [sit him]. He's such a great player.

"That one kid [Williams] is a hoss, there's no question, but we've got to do what's in the best interest of our football team and LeSean also, but just golly, he's such a good player. I just hope ... him not at 100 percent ... if he's close ...if he's at 80 percent, he's still a heck of a player."

McCoy seemed more open about the possibility of resting his hamstring this week.

"We got to look at everything," he said. "We'll figure it out. I'm not sure right now. I don't have a definite answer. We'll see what's going on."

"... That's part of football. Just got to find a medium between being tough -- and laying it on the line for your teammates -- and being smart."
