Opt outs in general are not always bad. But the Cubs are probably in a situation where adding another possible roster opening to 2027 is just not feasible. Hoerner, Suzuki, Happ, Imanaga, Boyd, Taillon, Kelly, Rea, much of their BP....it's a major chunk of the roster. They could resign one or two of them, and they might have internal replacements for one or two as well, but extensions will likely raise those salaries; how much will realistically be left over to replace these guys? And with whom? Many of these players look to be the top player in the market - so how do you get better?
You have to assume if the Cubs sign a player for $20m AAV that's the best player they're getting this cycle; losing that player on top of what they already are, has to almost be a no-go right now.
In terms of Imai's contract, I think this is especially bad for Houston. They pay the posting fee on the entire contract and what's the upside? If Imai is hurt or bad, he's stuck and if he's good he leaves. One year deals are rarely bad but Houston takes all the risk on this one. Owners shouldn't care about the money but we know they do.
