Don't get me wrong - I still think it's a pretty solid "no" on both Peraza and Simmons for the time being. But as long as one of them was kept, I agree with rico when he says we definitely have enough depth that Hart's simply not in a position to say "no" if someone were to blow him away. Say he gets an offer like I mentioned from the Mutts from someone and they're also willing to take on the remainder of Johnson's deal to get Simba. That'd be almost as good as the Kimbrel/Melvin deal, and would be awfully tough to say no to - especially when you remember that the target date for all this to be in place is 2017, not 2016.
Sure it's a bit of "pie in the sky" hoping, but what if the Tigers offered Steven Moya, Derek Hill, and Jose Iglesias for Simmons, Johnson, and Jim Johnson???
They're absolutely in win-now mode like the Padres were - they could desperately use pen help, haven't been blown away by what they've gotten from Castellanos thus far, and while Iglesias got off to a hot start there's little doubt that Simba would be a long-term upgrade. We'd get a cheap SS with almost Simmons-level defensive chops, the Tigers' version of Aaron Judge, AND a guy who profiles as an elite CF (55 hit tool, 70 run tool, 65 defense tool) - PLUS we'd clear Johnson's salary.
Not so sure I could say no to that. If Hart could get them to throw in Buck Farmer or Kevin Ziomek for Avilan, I know I couldn't.
