A friend I play football with was at practice last week. He told me he had the SAME EXACT operation. I said when was it done. He said 3 weeks ago! I was like "Wow, and you are back already?" He said he was walking the next day and then his knee swelled with fluid, they drained it and then he said it was like nothing happened. No, he isn't a professional and I was talking flag football

but the point is that for him it was like nothing really happened, though he did say
he had to be careful with cutting. (edit - I should add he had a piece of meniscus that was blocking his motion. He had to have the surgery, his knee didn't have full range of motion.)
I think that last part is why it's a 6 week thing and not 3 week. I think Lin could easily go sooner, but there may be too much of a risk there.
It's a two way street for pro athletes though. Yeah, they put more strain on their joints and such, but because of their training, protein intake, professional trainers available, computer assisted rehab, etc. - they are in better shape than most of us, so they heal quicker. Can't just take the negative, it goes both ways. But, we do need to be VERY CAREFUL with Lin, if he rushes back it can be bad.
Again, I stick with this being a minor surgery. As long as there are no complications, this is a very minor thing. Hopefully the damage is very minimal so the small loss of meniscus doesn't hurt him long-term - that can be the catch.
