Time will tell as to whether all these moves (adding Turner, Rogers; losing O Connell, Shaffer, etc.) are good but one thing seems likely to me: Rivera is the one directing these moves, not Snyder. Haskins lobbied to keep O Connell, but Rivera wanted his own guy from Carolina. Shaffer a long term Snyder guy, replaced with another Rivera contact from Carolina.
In the end, even though I really like O Connell, this is why I'm ok with bringing Turner in. Had Rivera come in and been forced to "keep the old guard" then we're back to Snyder running the show over the football people again. The fact that Snyder is allowing Rivera to bring his own people in to the demise of some of his own people...that's a good sign.
Side note: based on one random comment in Rivera's opening press conference, I heard some radio hacks claiming that "Snyder still had all say on personnel" but that does NOT appear to be the case...quite the opposite in fact. This is one of the reasons I listen to less D.C. sports radio nowadays.
Like I said, time will tell if these are good moves. In the meantime, I do like that Snyder is allowing Rivera to try it his way first...
