Maybe. But, I'll just say that 10+ teams interest in a good experienced coach in the wake of all the turnover over the years isn't much of a surprise to me. The potential talent pool at the position seems a bit questionable.Fair enough.
I'd agree with your assessment if we're talking about the Jackson from a few years ago, but not for an athletically declining Jackson.
And I'm higher on Harbaugh than you are. Since he's been called by 10+ teams, it sounds like the whole league is, too.
My guess is there was a time that Patriots wish they had held on to a declining Brady instead of a great coach in Belichick. But, oh well. It looks like things worked out for them now.
