While I certainly agree with the premise that Atkins isn't a good GM, I think it's shorted to suggest he's some s***** poker player beta and suggest he should have done A, B & C instead. Moreno had a 78 wRC+ in the 1st half of this year. If he was doing that on the Jays, while playing out of position or some s***, his value likely would have dropped significantly.
You can rip Varsho all you want, but he was coming off 7.1 WAR over his past 900 PA's (which is about a 4.5 WAR pace over a full season). He was also coming off a 119 wRC+ second half in 2022. If he gets off to a hot start in 2023, there's a good chance he's simply not available anymore - especially for 1st half limp dick hitting version of Moreno. And the longer we held onto Teo, the more his value drops. He was awful in April and May this year. If we kept him, there's a chance we don't get someone as good as Swanson for him.
Then you have to factor in that the Jays were in a "win now" mode. Trying to play one of the catchers 'out of position' or proceeding with a suboptimal lineup may have cost them games in a season we couldn't afford to do that.
Now of course there's also a probability that following your formula would have given the Jays better results - but you shouldn't act like that was a given, or use that as your reasoning to rip the guy when you little to no idea if your approach would have worked or backfired.
