Won't happen until Dolan sells the team. That's on the owner, not the GM. If he were YOUR boss you'd also do what you were told or you'd go find a job elsewhere.
Which isn't to say that that is the right thing to do or not.
I look at teams like Vegas and Tampa Bay and neither have built shit through the draft. Tampa has had TWO, count 'em, TWO 1st round picks in the last 7 years (27 and 30 OA) and are competitive every year.
Vegas has ONE person on their team that they drafted in the first round. IN THEIR HISTORY.
This isn't solely about developing youth.
And, to be fair, Drury has been hamstrung by players he didn't draft, players he didn't sign, and NMC's that he didn't hand out. That's changing in the past two years. Will Dolan be patient enough to see if it'll all work? Probably not. And then we'll have an other reset with another GM with different ideas and another set of coaches.
Personally, I'd fire Laviolette and that's something I would've found incredulous to say after last season but this team hasn't played team defense, aside from a spurt here and there, the entire year and that's what wins. And why we aren't winning.
