Per article, his injury was much worse than I thought. Kudos to Ryan for fighting back and playing thru pain. The common sense, however, should tell him to retire after the end of this season, if he doesn't want to risk his health in the future. But it won't happen. The "$$$" sign will prevail: milk it till the end, for 3 more years.
Hey, can't blame him. If I was in his position, I would do the same. You can't walk away from guaranteed money.
