The first three names I saw thrown out there for the Browns were Lincoln Riley, Mike McCarthy and Jim Harbaugh.
I don't think Jim Harbaugh is done coaching in the NFL, but I don't think the time he's leaving is now, and certainly not to go coach the Browns.
McCarthy makes some sense, the situation in Green Bay feels stale, and maybe they just need a new voice there. I kind of think it's the same in Pittsburgh, where they have a great coach, but the message is stale. All parties involved there could benefit from Tomlin going to Green Bay, and McCarthy coming home to Pittsburgh. Absent that, I still think McCarthy would take a year off over coaching the Browns.
If Riley wants it, that makes a lot of sense. Then again, he might not want it. I don't get it, if you can coach in the NFL, I would do it every day, just do be done recruiting, and kissing the ass of 17 year olds for 2 years on the recruiting trail, just to have them transfer the second you stop kissing their ass. But Oklahoma is one of those special jobs that doesn't come around all the time.
