Don't think Fleury was bad today tbh, they didn't get blown out so that's a step in the right direction.
I wanted Sully to experiment with the lines more a while back after putting HMK together to see what might work for the other lines, so I'm glad he has since, but I admit I was wrong believing Rust could cut it on the 1st line. Crosby really has to work to create anything at 5v5 right now, you never see anything come easy for that line. Fine with Sheary there as long as he can maintain the ice-time without a drop in performance, so I'm really only "worried" about that right wing slot for now.
Seems like the only combo Sully hasn't tried for any significant amount of time is Kessel on the 1st line so maybe we see that at some point. That said it might not be what's best in the long run barring something like Guentzel being called up early and picking up where he left off providing the bottom six scoring they're going to need for the stretch run.
They have time to think about it while they heal up though so here's hoping the coaches/front office brainstorm some possible solutions for the few remaining roster issues they have during the break.
