He's a career 37.5% shooter from the floor and 31.5% from three. Even allowing a gigantic margin of error that we could attribute to coaching turnover to play devils advocate, he still shoots horribly.
Can anyone find someone with a worse career FG% who's been in the league for more than a few years and was a starter?
Jason Kidd ALMOST qualifies, but not quite. 40% career FG%.
Of course I also disliked Jason Kidd as a player about as much as I dislike Rubio.
