Killorn-Johnson-Callahan seems like a poor man's version of the Whack-A-Mole line. But I guess, seeing as how they'll be pretty sheltered, they could work out.
I think Point would make more sense between those two though. Better vision than Johnson, playing with two guys who need a creative linemate.
Ultimately I think we're gonna separate Stamkos and Kucherov. If we can find a suitable playmaker for Stamkos (Point?), that would make us deadly at ES.
