Yeah only reason the Mets would balk at a short term deal for Alonso would be trying to save money/the position for Vlad next year. Alonso is going to get opt outs in his deal but there's no guarantee he will opt out (see Bellinger), and he's a much tougher player to trade given his profile (lumbering 1B/DH). With that said, I feel that's a rather pointless thing to do for the Mets. They have the richest owner in the sport, so worst case if they sign Alonso for 3 years with opt outs and he doesn't opt out, it's not like Cohen is going to have issues paying Vlad. Maybe Stearns just doesn't like Alonso, or this is all just a game of chicken that Boras is playing (using the Jays) to get the Mets to cave a bit.
