"It's all about being in the right situation at the right time," he said Thursday.

BEREA,Cheap NHL Jerseys, Ohio (AP) — Three months later, Robert Griffin III is starting anew with the Browns.
"That is what I have seen in practice," he said. "I wanted to really evaluate it all because sometimes, guys tell you they can do that, but they will not do that. We won't really know until Sunday, but I think what I have seen in practice is a guy who is ready to play. We will put him out there and go from there."
"The most important thing about that position is availability," Jackson said. "And I think he gets that. It (the shoulder injury was) unfortunate. We can't change that. All he can do is play now and show what he can do for this team and for all of us."
It's another chance to show doubters that he's durable and perhaps the beginning of a four-game audition to prove to the Browns that he can be their long-term answer at quarterback.
"That doesn't change just because they name you the starter or just because you're playing. It's an everyday thing. Not just a Sunday thing,Wholesale Jerseys.
Griffin wore a "No Pressure, No Diamonds" hooded sweatshirt when he met with reporters. It's a motto he first adopted while winning the Heisman Trophy at Baylor, where the Bears turned around their program and it's a mantra he lives by now.

But after showing coach Hue Jackson in practice that he's healthy and ready,Cheap Jerseys Free Shipping, Griffin will make just his second start since 2014.
Jackson held off until Wednesday night before telling Griffin he would start. It's the sixth quarterback change this season for the rebuilding Browns, who have been overrun by injuries.

Griffin, who didn't make it out of Cleveland's season opener without getting hurt, will make his second start on Sunday when the 0-12 Browns host the Cincinnati Bengals.
"You don't want to put that kind of pressure on anybody. Again, it's his second game in a little over maybe two years. So hopefully it will go right. But if it doesn't that's OK, too.
In his debut for the Browns, Griffin completed 12 of 26 passes for 190 yards and an interception. He got hurt in the fourth quarter when he was hit while trying to run out of bounds, taking an unnecessary hit near the sideline.
