It makes zero sense to extend him now other than for cap room.
If he plays well this year and goes on a nfc title game/super bowl run…. Then you can pay him.
Even if he is the regular season mvp…. Another post season poor performance you think teams are gonna pony up a lot of cash for him. I doubt it.
But let him prove he can win something before you extend him. He’s a great person but I don’t feel bad for a guy that’s made the money he’s made in his career. He’ll survive not playing without an extension
