Interesting. Katchouk is one of those guys who hasn't quite seemed to embrace that 4th line banger role consistently enough to be super appealing there. But he's cheap and when he plays with a bit of hunger, he can be a plenty effective 4th line grinder.
I doubt he's claimed. But it seems like both Detroit (with that connection) and Pittsburgh (Dubas - Soo connection) are in the market to tinker or add a stopgap. Due to injuries, staleness, whatever it may be. I could see either putting in a claim, since he's a minimum dollar gamble with minimum "downside" and a tiny little dash of potential upside if he develops some more consistency on a better team.
I'd rather have Katchouk than Poolparty pretty easily. Especially since one guy is in game shape and the other guy has just been sitting around recovering from more hip repairs and already had absolutely zero agility in his skating to begin with.
