After further contemplation..
Meh.
Relax. He is either ready, or not. If he feels good and doctors agree, then he should be playing. Can he get hurt again? Sure. Can he get hurt next season? Sure. Can he get hurt on any given play? Yep. Can he get hurt getting out of the shower? Yes, he can.
Message board docs have ZERO insight into his stability, leg strength and most importantly, mental readiness. The ligament heals more quickly than you might think but the supporting muscles strengthening and rebuilding is the majority of the rehab process. Before beginning true exercise the knee has to be stable and pain free. Of anyone, TM has the insight into how ready he is and it won't be just team doctors, but his own, that will clear him.
He can be 100% and go out and play with no issues, or injure his knee on the first play. Neither of those outcomes means he was "rushed back" or "completely ready." There are things I still wear my brace for even though I'm fully healed and mentally pretty confident in my knee, but if I am planning to hike I will wear my brace because of potential instability but even that is a mental hurdle. There's not a lot of science to show the brace protects from future injury, though it suggests it.
Yes, a lot of people who injure a knee come back later and get it injured again. That's not a shock. Once you sprain an ankle, get ready for future sprains.
Bottom line, if TM is ready then he's ready.
