I think De Leon + Alvarez + Filler seems the most reasonable. Bellinger would be nice but I think the plan has to be Sano taking Mauer's spot at first once that era ends, so I doubt they are targeting that enough to be stuck on him. Alavrez is a blue chip wild card with a ton of ceiling and long ways to go, Alex Meyer-ish? De Leon is ready and has a solid #3 profile with some upside that could be realized, he reminds me of Scott Baker with his flyball/ control/ k makeup. For filler there a couple good looking catching prospects and wild card arms down the rankings. It doesn't bring back the A+ immediate arm that everyone wants, but De Leon offers immediate relief and Alvarez offers a big potential prospect. I hope the Twins pull the trigger if this is close to the terms, we need future controllable pitching much more than a veteran power second baseman.
