Was going to post this in regards to the 3rd line. Joseph scored 12 goals this season and Coleman had 14. Coleman had more assists but Joseph is a decent enough goal scorer to fill that void, he scored 13 his rookie year as well. He's fast and hits on the forecheck, he's not as strong in the defensive zone as Coleman and not as strong in the cycle game. But Coleman will probably cost 3M+ more than what Joseph will next season. Offensively he's better than Goodrow so if we lose him Joseph can make that line a little more offensive but they won't be a shutdown line any longer.
You can always throw Killorn - Cirelli - Gourde together for the shutdown line. Put x - Colton - Stamkos as the other scoring line. That x could be several players depending on what moves we make at the ED and draft. Could give Barre-Boulet a look, Joseph or even a Raddysh or Katchouk.
I have a big issue with Josephs consistency. Sometimes he looks like a good top 6 player and other times he just disappears. If he found some consistency he'd be amazing.
I see where you are going with the Cirelli shutdown line. If we lose Palat, I'd like to see Stamkos moved up. I feel like Stamkos isn't very effective next to Cirelli.
Our lower lines are going to be a mess, but I'm ok with that
