The New York Knicks signed veteran point guard Kemba Walker in the 2021 NBA free agency with the hope that adding him to their roster would make them a more competitive team in the Eastern Conference. Unfortunately, things didn't go as the Knicks expected as Walker struggles to remain healthy and become consistent on both ends of the floor.As of now, Walker is facing an uncertain future in New York and multiple signs are pointing out that he would be moved before the 2022 NBA trade deadline.Kemba Walker To Houston RocketsOne of the potential landing spots for Walker this season is the Houston Rockets. According to a source who spoke to A. Sherrod Blakely of Bleacher Report, the Knicks and the Rockets could explore a trade deal involving Walker and John Wall."A source close to the Knicks indicated New York may also have a potential trade partner in the Houston Rockets, who are eager to move John Wall," Blakely wrote. "Like Walker, Wall has had his share of injuries that have factored heavily in him not playing at the level that made him an All-Star from 2014 to 2018."Knicks Take A Gamble On John WallSwapping Walker for Wall would be a huge gamble for the Knicks. Similar to Walker, Wall is also on the wrong side of 30 and has dealt with numerous injuries in the past years. Just last season, the veteran point guard suffered a hamstring injury that put him on the sideline for a long period of time.However, Wall seems ready to return to the court soon. Recently, Adrian Wojnarowski of ESPN reported that Wall expressed his desire to rejoin the Rockets in the 2021-22 NBA season.John Wall's On-Court Impact On KnicksUntil he sets foot on the court again, it's hard to say if Wall would be an upgrade over Walker at the Knicks' starting point guard position. However, if he could return to his 100 percent healthy and bring back his old self, Wall would undeniably be an incredible addition to the Knicks.Wall would give the Knicks a prolific scorer, a great playmaker, and a decent floor-spacer. Last season, he averaged 20.6 points, 6.9 assists, and 1.1 steals while shooting 40.4 percent from the field and 31.7 percent from beyond the arc, per ESPN.Why The Rockets Would Trade For Kemba WalkerLike Wall, Walker won't have any use in Houston, especially now that they are still in the initial phase of the rebuilding process in the post-James Harden era. However, swapping Wall for Walker would be a huge help for the Rockets financially. Though their contracts have the same length, Wall's salary is almost five times bigger than Walker's.However, the Knicks are definitely aware of the financial consequence of the trade. If they decide to push through with the deal, they would likely require the Rockets to give up some of their future draft assets.
