The key to this particular deal seems to be that the big money is in the team options which they wont pay unless he's awesome. I think this one favors the team slightly since his main value is defense which should project consistently better than all or nothing power hitters. If he gets something like 0.5 Owar and 1.0Dwar per season that might already be worth 4mil these days, idk.As teams start to get thrifty in free agency this will be the next big way some teams will piss away tons of money. White made a great move, deals like this are great for the player, it will give them more serious consideration in spring training and a clear path to the show. Teams will start to lose big on some of these deals when "can't miss" guys start to miss. I suppose it's a smaller gamble than $100 mil on a 30 yr old guy but somehow it still seems riskier to me.
On the flip side, "bats right + throws left" players are an ungodly crime against humanity. Throw garlic at this asshole!
