Alright here's what I'm thinking for the next few games at least,
Keep Laf with Trocheck & Panarin for now on the 1st line, bump Smith over to LW on the 2nd line with Zibanejad and promote Berard to 2RW. He's earned it. Then run a 3rd line of Cuylle-Chytil-Kaliyev just to test the waters. Kaliyev has seemed to play good with a play-driving play-making center like Danault and Chytil is one of the best at that on the Rangers. Give him 2nd PP Unit time while we're at it too.
If/when Kaliyev starts potting loose pucks that nearly everyone on the Rangers can't seem to pickup or read, promote him into the top-6 group and give him as many cups of coffee as you can with Artemi Panarin.
