He's signing for the vet min. If he gives anything - and he's still a beast on defense - it'll be worth it.
I think he's a scrub as much as anyone else. But the guy was our enforcer (when there) in the middle after Perk, and he seemed to like hurting people. Who can argue with that for the min?
People are suggesting we sign Darko, for some perspective... I'm not suggesting it's a good move to sign him, but it's no worse than Darko.
