Defense is always going to be somewhat linear to their partner.
Based on eye test, id agree lybushkin is the worst dmen on the roster(not that i think hes awful, just isnt great either)... and thats going to drag his partner down a bit.
Just like Gudas based on eye test is prob the best defensive dmen on the team, and hes going to bring a guy like vaakaninian up whos played with him majority of the time, and not for nothing buts hes played a very safe/good game.
Eye test on fowler matches too, hes left something to desire offensively... and hes always going to be questionable defensively.
When drysdale is back id love to see
Fowler Gudas
Mintyukov Drysdale
Vaaks Lacombe with lybushkin coming in vs heavier teams
