I can't see a reason why LA give up Clarke in a trade for Provy, who they have cheap for 2+ more seasons, plus what 6 more years of control? It's a non starter from their end imo. Since playing he's been one of their best defenders, leads the d group in xGar/60.
The most likely target out of LA is going to be one of there 21-22 year olds RFA's or soon to be. That's where they have depth, and where they may have a log jam this year or next. They have 2-3 talented centers in Vilardi, Byfield, and Turcotte, and could spare to loose one of them imo. If you're going to give Byfield a pass on missing dev time, so have Turcotte - he's played only 70ish games in the last three years.
I my mind, if you get a player out of LA, it's just likely to be a youngish forward, who will need a new deal in a few years. Or, it has to be a 1st round pick.
