The Melo Era in Knicks could've played out so differently if he simply waited to join the team in free agency. Melo got paid, but he underestimated the incompetence of the Knicks front office.
STAT put up MVP-caliber numbers for a couple of months before his knees exploded (right when the Suns said they would) and the Knicks had $20 mil chillin' in a suit for five years.
Jason Kidd was arguably the best PG during Melo's entire Knicks run, but he was 40 years old and went scoreless for his final ten games in a Knicks uniform.
Tyson Chandler was a solid get, but his offense was non-existant, he had the immune system of a small child with the legs to match:
His tap-out rebounds were okay, I guess.
JR Smith was Melo's second option with STAT sidelined, so that went as well as you'd expect it to. He was good for the highlights, but he wasn't consistent enough.
Steve Novak was one of the best shooters in the league, but once defenders realized that he couldn't put the ball on the floor, he became a waste of space.
Bargnani:
They traded their 2016 First Round Pick for that man. Yes, he injured himself on that play.
Shumpert's promising Rookie season got cut short when he tore his ACL (the same knee and day of D Rose, oddly enough) and he wasn't the same since. Nagging injuries stunted his development, so Iman did the NY thing and became a rapper.
Porzingis came around too late to really matter, but he had his share of issues as well. He was a 7'3" dude that was too weak to bully anyone in the post and his numbers fell off a cliff after November/December. Who knows what he'll be once he comes back from his ACL rehab?
There were plenty of Melo highlights in the Knicks era, but that's the only positive that you can extract from those 5~ years. The Knicks had chances to correct course (There were talks of trading Shumpert for Lowry back in 2013 or so), but things didn't pan out. At the end of the day, there's a good chance the Heatles would've run them over all the same so...
Melo was doomed.
