It's about time (or too late) Tyron looks himself in the mirror and really figures it out that year after year something bad happens to his body, and tells himself whoa, what was or am I thinking. He himself has to get a grip.
In my opinion, the smart move is just too retire while hopefully he can walk a straight line.
This kind of injury just looks to be his body giving out, so not only is recovery more difficult but it is mostly likely that trying to come back will lead to another injury. I think he's done at this point, will attempt to come back and hurt something else and then retire. I'd admire the years that he's given us, but his body is saying it's time to quit.
Tyron Smith is one of my favorite players on this team and has been since we took him, I think he should consider retiring, on that note, I doubt he plays this season at all.
