TWO things happened: They hired Mac and they dumped Cam.
For me, whatever misleading euphoria I might feel relates entirely to the dumping of Cam, a hopeless waste-of-space dead end if ever there was one, whose absence in itself is a cause for hope. Cam's banishment was a necessary condition for future success, but not a sufficient one.
Which brings us to Mac, who offers the promise of success but not the certainty. First off, he IS a rookie, and with rookies you never know. Second, I do worry about his stamina and his ability to with stand the punishment physically. Let's face it: he's squishy. This can certainly be addressed over time, but as he's a starter NOW, it's a problem now. I don't like the look of that knee brace either.
On balance, I think he'll do well for a rookie, which means chances of making the playoffs sit right at about 50/50. If there are injuries, of course - as it seems there might well be given the history of a number of our players - then the odds decline accordingly.
