And again, it doesn't matter who starts, it matters who finishes and Gortat finishes almost every single game.
There is another factor here. With Gortat pulling down 17 rebounds, Lopez with 3 actually outrebounded Nash for the first time in a long time, if ever. Nash had 1 board.
Nash not having to rebound, leaving him to save his strength for assists, scoring and some defense, will tend to keep Nash healthier.
Lopez's time on the court is always with Nash (to start the 1st and 3rd quarters), with very few exceptions, such as a few minutes when he played in the 2nd quarter vs. Boston last night. Even then, if I remember right, Nash was on the court.
Gortat, who played his thirty minutes with both the starters and the bench, needs Nash less than Nash needs Gortat, to keep him refreshed. In other words, Gortat's presence has more of an effect on the Point Guard position than Lopez's presence.
And what is more important to us than Nash's playing at the top of his game? (With Gortat's rebounding and defense proving to be a solid second.)
BTW, not only did Robin Lopez's three boards beat Nash last night. It also beat his twin's one rebound. Wow! Of course, Brook outscored Robin 28 to 11 (in a blowout loss).
