I'm not sure I follow the difference, when you say a guy can't stay at short, aren't you bascially saying he's a less than average quality SS - either his range or his arm is going to cost you enough there that you are willing to play a worse bat in his place and move him somewhere else?
Just looked back at the MLB scouting lists back to 2024, McGonigle was consistently 50/50 arm/glove. Just for comparison, Sweeney was 55/50 as a prospect for the Dodgers.
OTOH, I think for left side IFs, sometime throwing velo gets over emphasized and total time to 1b may be harder to quanitfy. For instance on the great play last night, a guy with a cannon might have set his feet and made a harder throw, McG looped the throw a bit but got if off very fast. All that matters is total time to the 1B's glove.
