Honestly, if Gilbert was even half the player he used to be, I would love him on this team. He is completely insane, but he also is a competitor.
However, the Gilbert that has shown up recently is not even a shadow of his former self. He is just terrible.
The knee injury sapped all of his quickness away, and he just became a total liability. He no longer could get open shots, and while he was always a good shooter, he was never good enough to be a true marksmen, if he can't make his own shot (like a Reddick type).
