I think his price is going to be high due to the number of teams looking for an IF bat and the ridiculous season he's having. He's gonna fetch a price higher than your average rental IMO.
Does that mean the Cubs should be out? Maybe. But the thought of adding a power righty bat is so tantalizing. Not our biggest need, not our second biggest need, but given how lefty dominant our best bats are, the fact that 2 of them are significantly worse against lefties, our poor bench options, etc. I don't think the Cubs are wrong to be looking at Suarez. I would just have a line that you don't cross if other teams go higher, especially if those resources are also needed for a pitching trade.
