Gilbert appeared in eighteen games for the Los Angeles Kings, picking up a goal, four assists, and a three-game suspension in his tenure. If you want evidence of how he fell out of favor in Los Angeles: he played 7 games in October, 6 games in November, 4 games in December, and just 1 game in January.
The move makes sense when considering that Kevin Gravel and Brayden McNabb have grabbed a hold of the 5/6 spots on the blueline, but it makes less sense given that Matt Greene was placed on injured reserve, just yesterday.
