It's an interesting trade offer in that it really does work extremely well for both sides.
But man oh man, you'd better trust the hell out of your scouts.
Profar's ceiling on offense is probably not as high as O-Tavs, but it's close. I actually like his approach more than I like Tavaraez's. But Tavarez has the body and bat whip to be a big time middle of the order hitter with outstanding contact skills.
As a run producer, I don't care about your BB rate if you're still commanding the strike zone. Tavarez seems to do that nicely. But ultimately, he's still just a corner OFer. If you can get a 25/25 SS with a plus glove, that's as valuable as a 40 HR OFer. Or at least damn close. And in a system with a lot of guys that can hit but very few that can play SS, it's a trade you have to consider.
I'd rather trade Holliday for Andrus, but I don't see that happening.
If you can't draw a crowd, draw dicks on the wall.
