the problem this franchise has had going back to Ewing & even before Dolan was they (FO & ownership) thought we were 1 piece away from competing, getting over the hump, to the next level- and they made bad decisions.
I don't want to turn this into a trade Melo flame war 
But at some point over the next few years, Phil or whomever comes after him, may need to trade someone like Melo to restock, and build out. It could even be this year with someone like Afflalo, Lopez, KOQ, etc.
Sometimes getting ahead requires a step back.
But to the original post - this franchise has a legit future for the first time since Ewing.
