This is starting to feel a bit like the offseason FA "win" of Rondo, Belinelli, and Koufos. Nothing totally wrong with it, but it's a big "ehhh" that will be trumpeted as something important. I'm OK with Dennis as a guy in our rotation. Rather not him start, but if that's the best we can do so be it. I definitely wouldn't be looking to sign Russ. Yes he's a non-stop competitor but often to his own detriment and hasn't really been a positive difference maker for a number of years.
At the end of the day, I'm willing to accept some level of head scratching on the decision making if the overall goal is to turn us from a collection of nice guys with a focus on pretty offense, to a hard nose in your face defensive team.
