That's a nice thought, but if you were suspended for a year from your practice, and I were a potential patient, I'd sure the heck want to know why.
It's just like defendants that take the 5th. Sometimes it's an advantage, sometimes its a detriment. But, he always has the right.
How a potential NFL QB can take the 5th about some issue (and BTW, how do you know its medical... nobody has confirmed anything?) that has him out of football for a year and a guessing game as to if he'd ever be back, I don't know.
We can talk about legal rights all day long. But this is a football team, and these guys get paid a lot of money, and a coach has to be able to count on them. So far, Bennett has shown he cannot be counted on. Can he redeem himself? Don't know. But I put the chances at low.
