LeBron, Kawhi and Davis in the same rooster is unfair to put it mildly. Can't see any team threatening the Lakers if they stay fit, the backcourt gets strengthened and the bench (depending on the cap space left) will be strengthened as well. I am sure that some veterans and proven winners would love to jump onto the ship and sign 1-year contracts for the chance to win a ring.
Team chemistry and everything aside, I don't really see many teams in the West capable of beating the Lakers over 7 games if the above occurs. The Warriors are probably worse off than the Rockets as of today on paper. Denver, while incredibly talented, I don't see them beating a team with a fit LeBron (out with a vengeance to prove himself after the injury and missed playoffs), Davis and Kawhi.
Exciting times and it would be incredible if the Lakers managed to land Kawhi. I have never been a fan of projects like the old Heat or the Warriors most recently but after 10 dreadful years, I just want to be a contender again. The neutrals will hate it but most of you guys hate the Lakers regardless.
