Knees and hips do not respond well to being reconditioned for an entirely different usage at age 40. Just getting out of the snap takes an entirely different muscle grouping than what a tackle is used to. It would be beyond moronic to even consider moving an OT to C at age 40. It's also not about the mashing, it's about keeping safe in the fray. 40 year olds do not have the flexibility to get rolled up on as an example. Relearning a new position at age 40 does no one any good, not Stan, not our team. If it was as an emergency thing sure. But how stupid would a team have to be to even consider taking their best OT and converting him to C at age 40. I can't put into words how dumb and short sighted such a decision would be. Moronic doesn't begin to cover it. We would be putting Stan at a position completely new to him, asking him to learn how to snap, how to use his body completely differently than all his pro career for what? The guy is 40...there is no long term benefit whatsoever.
Like I said this isn't about his ability to get it done, it's about his age. He plays OT until he cannot do so anymore. Any plan other than that with a 40 year old player would hurt the team and be beyond moronic.
