The Lakers have Luka Doncic and Austin Reaves, but Robert Horry believes another player will ultimately determine how far they go this season.Walker Kessler.The three-time Lakers champion has named Los Angeles newest big man as the teams biggest difference-maker heading into the 2026-27 season, even placing his importance above Doncic and Reaves.When you watch what Walker Kessler brings to the game, hes so incredibly skilled and we havent had a big since AD that can block shots like that, pop out for threes, Horry said. So I just hope he stays healthy Him missing damn near all season, how much rust has he developed?Kessler arrived in Los Angeles this offseason after the Lakers acquired him from the Utah Jazz in a sign-and-trade deal. Los Angeles gave up two unprotected future first-round picks and two first-round pick swaps in the move, while Kessler landed a four-year, $130 million extension.Its a major investment, but Horry believes the 25-year-old could be the piece that unlocks the Lakers.So its going to be really interesting to see what he can do because he is the key, Horry said. Not Luka, not AR, he is.Kessler had already established himself as one of the leagues most productive young centers before injuries disrupted his 2025-26 campaign.During the previous season, he averaged career highs of 12.2 rebounds and 2.4 blocks per game while adding 11.1 points and 1.7 assists. He was producing at a similar level last season before suffering a torn labrum that brought his year to an early end.His arrival also addresses one of Doncics biggest requests following last season.Doncic made it clear he wanted the Lakers to add a big man during the offseason, and the front office responded by making Kessler one of its biggest investments.Los Angeles is now preparing to begin a new era following LeBron James departure, with Doncic taking over as the face of the franchise and Reaves remaining alongside him.But despite all the attention surrounding that backcourt duo, Horry believes Kesslers health and production could ultimately decide whether the Lakers become legitimate championship contenders.For a franchise chasing its 18th title, Horry sees the new big man as the key.READ MORE: Charles Barkley Reveals Plans to Walk Away From Inside the NBA
