I'd rather err on the side of caution. If that means "broad brush" criticisms, so be it. I'm good with that. I know that you're correct that each case is unique, but I also know that these things more often that not don't get better, surgery or not. It's tough enough for regular people to deal with, it's quite another asking a professional athlete whose body takes a much more physical pounding to do it.
And personally, I don't look at age as necessarily a positive factor or advantage. After all, age didn't prevent either Lawrence or Tapper from suffering these back injuries in the first place, right? I see no reason to assume that age would prevent them from occurring again.
