On Friday, explosive news leaked out of Cleveland that superstar point guard Kyrie Irving asked the Cavaliers for a trade last week.According to ESPN’s Brian Windhorst, Irving no longer has a desire to play alongside LeBron James and instead wants to be the main face of a franchise elsewhere.It was also revealed that Irving listed four teams that he wouldn’t mind getting dealt to, including the San Antonio Spurs and Minnesota Timberwolves from the Western Conference as well as the Miami Heat and New York Knicks in the Eastern Conference.Since the Knicks have openly been looking to deal Carmelo Anthony for quite some time and since the Cavaliers have been a rumored possibility to land Melo’s services, ESPN’s Ian Begley was quick to relay that the Knicks have a lot of interest in landing Irving, who would likely become the instant face of their franchise.But, there’s one player that’s off-limits in any possible negotiations.“The Knicks, obviously, have strong interest in Kyrie Irving (just like 29 other teams) but I'm told people in the Knicks front office would not be willing at this point to include Kristaps Porzingis in a trade. Some with the organization would be willing to include future first-round picks and Carmelo Anthony in a deal for Irving, per league sources,” Begley reported.If you recall, Porzingis’ name was floated around before the NBA Draft as a possible trade piece, but it appears that that mindset disappeared, along with former president of basketball operations Phil Jackson.On Twitter, Porzingis “liked” the following tweet of Irving in a Knicks uniform.

Therefore, it seems as though he approves of the possibility.

Although it seems like a foregone conclusion that the Knicks would accept some form of a Irving-for-Anthony trade, one factor is uncertain: Melo’s no-trade clause.

As Frank Isola of the New York Daily News pointed out, however, there’s no certainty that Carmelo would accept a deal to Cleveland just for the simple reason of leaving New York.

“Anthony would have to waive his no-trade and there is no guarantee that Anthony would do that to join a Cavs team that didn't have Irving,” Isola noted. “Also, Anthony probably knows better than anyone that LeBron is leaving next July.”

“Carmelo could opt out of the final year of his contract next summer and become a free agent himself but he'd be giving up $25 million. If he were traded to Cleveland and stays for two years, his teammates would be J.R. Smith and Iman Shumpert but not LeBron and Kyrie. Basically, he'd have the Knicks without the Manhattan lifestyle,” Isola wrote.

Ultimately, the Cavaliers have the final say in this situation. Since Irving is under contract for another couple of seasons, he might be forced to stay put if the team is unwilling or unable to grant his request. Or, if they decide to deal him, they’ll be able to determine exactly where he goes since he doesn’t have a no-trade clause.

Therefore, the four-team wish list is essentially meaningless, but anytime any big name mentions playing under the bright lights of Madison Square Garden, it’s sure to catch everyone’s attention.
