Ultimately, it's about depth when you want to build a winner. I don't want to become a team like Pittsburgh, with star power up the middle but not much elsewhere. You want to have a solid team throughout, with a deep forward corps and a solid blueline, which we look to have right now...star power on top of it is just gravy.
I've been thinking about this a little bit lately and I'm kinda nervous with TM's "obsession" with McDavid leading him to gutting what's been put into place for him (Reinhart, Girgensons, Ristolainen, etc). It's probably just the "hoping for the best but expecting the worst" side of me (which somehow didn't come out during the tank race). If we win the lottery, great. If not, build around Eichel and what we already have.
I'm sure GMs have enough sense to not trade away a pick when a Connor McDavid is there for the taking, and I hope that TM accepts where the lottery puts us. Of course, if you can get it done with secondary pieces (Grigs, NYI 1st, Larsson, etc), then by all means go ahead...but that obviously isn't happening
