If Briere wants to make a statement that it's his team, he'd at least use the cap savings from York/Cates to go long-term with Frost on a deal that could be a steal 2-3 years from now. Briere is the chief proponent of Frost in the organization, so bet on it.
Unlike O'Connor, so confident Frost is bad on the PP, Frost's PP work has thrived at every level, and I believe that's the player with the most scoring meat on the bone -- at every strength. It's almost like the PP coaching and usage has been a league worst mangling.
If they further bridge Frost, so he can prove until age 35 he's not a toilet seat to John Tortorella, the person wearing the pants in roster control becomes that much clearer. There's Michkov, there's Konecny (who might not be here in 12 months), and then there's Frost in my ranking of most purely skilled players in the organization.
