I consider myself to be much more of an optimist than a pessimist in life. But, I'd be lying I said I wasn't if concerned about this management and what their going to do in the next few years.
Fletcher has said a few things throughout his tenure that I have perceived as positives. He's referenced, at least to some degree the use of 'advanced stats' to inform him and the coaching staff. He kept the scouting department together, which has been pretty good for a while now. He doesn't seem to hold onto sunken costs (Hartman, as an example).
However, he's also provided some real head scratching moments. Weird buy-outs, paying a bit too much in contract negotiations, paying too much in trades, signing guys like Stewart, trading for Thompson and Grant.
Fletcher has inherited a top 10-15 on-paper roster, and even if he doesn't do anything this year, it's going to be better through player development and getting healthy.
I very much worry that the moves he's going to make are going to hurt this team. So far, he hasn't shown, to me anyway, any area of above average general managing. I'm not excited about his future tenure with the club. I hope he can prove me wrong, but I'm not holding my breath.
