Look, Shaw has been capital B Bad, the expected stats show him as hopefully being mediocre to average, but we're a long ways off from Good. I get that, and Suarez, with all his overperformance, is clearly an upgrade.
But if the Cubs are an F1 team with two cars, one of them is the best car in the league but has a crack in the windshield, the other one is middle of the pack at best and a couple wheels are about to fall off. We should probably fix the wheels before we fix the windshield.
