Five years after the bounty scandal, the man at the heart of it is making jokes about quarterback injuries. Browns defensive coordinator Gregg Williams, who has had a resurrection to his career that would impress even Marv Albert, tiptoed back down the “remember me” path on Friday when discussing Titans quarterback Marcus Mariota, who played through a hamstring injury on Monday night. “We will see how healthy he is,” Williams told reporters. “We have played some very mobile quarterbacks. Marcus is extremely mobile. He is very well coached. . . . When we are playing those kinds of guys, we are pretty well versed on making those decisions and trying to make them do what we want them to do, but he is very dangerous when he is out there. I hope his hamstring is hurting a lot.” Williams laughed, but his history makes it a little less funny.
