Dougie right now this second might not be better than Weegar coming off a very serious injury, but if we're looking at his play last year and the year before, I think it's clear he's a superior defenseman.
He's got a rep for being bad defensively, but the numbers just don't show it. He plays a standard workload, and doesn't give up goals at a substandard rate, while driving possession metrics very strongly. He's prone to occasionally getting caught flatfooted because he's not a particularly great skater, and I think those are things that people remember, when his normal, boring, quality defensive play gets overlooked.
At the same cost, assuming some semblance of health, I'd take Dougie every time. And I like Weegar a lot.
