Absolutely. If he holds to going year by year as a free agent, he is ideal for mid market teams. You don't get saddled paying for any more than 1 bad year at worst. As for the off field stuff, his team mates won't care if he produces on the field.
I wasn't heartbroken he went to the Reds. Just because Kepler had his number for a bit doesn't mean he isn't a very good pitcher and Kepler would continue continue to hit bombs off of him...
I wish the other parts of his game were evaluated, i.e. defense and baserunning. It would give a more balanced look at his true value. People see the B.A. and get all excited, but he's a below average defender and doesn't have good speed.
"The value to a team of a fire-throwing reliever versus a top-of-the-rotation starter can be debated." Uh, no. There is a reason that aces get paid a ton more and get longer contracts than a closer. They are a LOT more valuable.
The problem with waiting is you don't know which teams will be sellers at the deadline. There might not be anyone that would be what you want at that time, and the cost usually is higher at the deadline.
