It seems like they've got PTSD from losing center depth in recent years, so they stockpile them and move the surplus to wing.
Not sure if this is good or bad. I'm leaning toward bad, as it may not be worth it to hoard those nuts just to have a mid 2-3C available if needed, which means you slot in a lesser winger from Hershey or the press box, after playing a center out of position in the first place.
Seems like a lot of half-assing when you could just fill your slots with the best possible players at each position, which means no moving centers to wings just to keep them around. Go get (or promote) some true wingers instead. Then deal with injuries as they happen.
