A 3 year contract on ALR projects to be REALLY bad in year 3 especially since most contracts are backloaded. I wouldn't just assume that's a tradeable contract by any stretch especially since the Dodgers already have Adrian Gonzalez so probably can't be fooled into taking ALR's contract.
If it's "That' bad, then you just release him. There's no salary cap - if it's year 3 of a 3 year deal - meh - I'm not so worried
