Do you give up Profar for him?
I think so. What's Lee got left? 4 years on his contract? That gives you a 4 year span with Darvish/Lee at the top of your rotation and Holland/Harrison also locked up for multiple years. Plus the bullpen which has been the strength of the team thus far has some really promising young talent( Robbie Ross, Tanner Scheppers, Martin Perez)
With that level of pitching you are going to be in the hunt pretty much every year. As I stated before I'm a big fan of Ian Kinsler, he's basically the heart of this team plus that power at second base is rare. And with Ian and Elvis Andrus locked up also for multiple years I say you trade Profar for either a starting pitcher or corner outfielder with good power. As much as I love Profar's upside I just don't think his value is with this team in the short term future.
