Borchard has a higher ceiling imo, but thats cause he's an awesome all around player.
I think Lee can turn into a .300 hitter who hits 25-30 hr's, walks 100 times, and knocks in 90-100 runs in the back of the order or the 3 slot. I kind of see him being a similar version to Frank, not near as good by all means cause Frank at his prime was amazing. I do see Caballo making an All Star game as a DH though.
Now Borchard he's going to be an amazing run producer, but may never hit .300 but will be a gold glover.
