There are a lot of Pac-12 players that made big improvements this season. Here are some of the potential candidates for most improved Pac-12 player.
Jordan McLaughlin, USC: The Trojans had a very down year in 2015, but they recovered with a tournament-capable season thanks mostly to the improvements of McLaughlin. In addition to being a great distributor, Jordan went from one of the worst shooters in the Pac-12 to one of the best, and USC's offense leapt nearly 200 spots in efficiency.
Michael Humphrey, Stanford: By traditional metrics, Humphrey is a very popular candidate. He's been one of Stanford's best players and has fueled their defense when their offense hasn't been able to get out of neutral.
George King, Colorado: One of my favorite stories of the season. After being injured last season, King was forced to step up in the absence of Xavier Johnson. And boy did he ever. King is one of the biggest reasons Colorado is on the verge of the NCAA tournament, becoming one of the best shooters in the conference.
Jabari Bird, Cal: The Golden Bears were floating on the tournament bubble for much of the season. Then Jabari went off in February, with a scorching Steph Curry-lite performance from downtown. Cal went perfect in February and are March Madness bound.
Dillon Brooks, Oregon: He might win Pac-12 Player of the Year, so if he does that it's unlikely he'll capture both awards. But Brooks took huge leaps this season, particularly offensively, and is the heart and engine of these Ducks. He could be the biggest reason Oregon captures a Pac-12 title.
