Gainey's going to go after a defender or do nothing, I think.
I have a feeling that Mathias Ohlund might be an option if Vancouver slides - veteran player, he's not the player he was before, but he's still a top 4 guy and impending UFA - the Canucks don't want him back. O'Brien's bad news, his positioning is terrible and he takes way too many lazy penalties.
Other options...Tom Preissing is a frequent healthy scratch in LA and can probably be had for a late round pick. But he's lackluster defensively and a 6th/7th defender + powerplay specialist at best. Derek Morris makes sense, strong hitter who eats up minutes, and is probably the ideal candidate (after Bouwmeester

), but the Coyotes are messed up financially and desperate for the playoffs.
