He is for sure, certainly one of the elite generators of chances and pure scorers -- when 55 is on his game he must be very difficult to contain.
FWIW, I thought some of his best plays against FLA were in his own zone, backchecking to break up a play, and then again on the PK, coming back and slowing things down to hand over to PP2 IIRC.
He's also a big guy who tends to spin off a fair few hits -- not as elite in that category as KFC, but few are -- and should be a good bet to adapt his game and perform well through the end of a reasonable next contract, a la newborn Wheeler, if he decides he really wants to be here.
So IDK. He might work out well, or he might want to test the market. He'll definitely have the opportunity if he keeps this up.
