Gula was nowhere near their worst D man.
He's their big stay at home guy, not brought in to set the world alight.
Obviously budget will be a factor and maybe he was paid more than other guys?
He has their best +/- of any player this season, (excluding 1 game O'Connor)
When they're carrying guys like Johnson:

Who looks on paper an incredible signing but is not performing.
I do agree that the worst goals against team in the league needs wholesale changes, so i guess this isn't a bad start for them.
