Miller, 38, is a favorite of new Kings coach George Karl, spending two stints under him in Denver (2005-06, 2011-13). He averaged 3.6 points and 2.8 assists in 12.4 minutes per game in a reduced role for the Wizards.
Sessions, 28, posted 5.4 points and 2.7 assists in 36 games for the Kings.
The Kings get out from an extra year of Sessions' contract, shedding a replaceable player and acquiring Miller, whose deal will expire after the season. His relationship with Karl will ideally make the transition smoother. This deal has less to do with his on-court impact and more to do with transitioning to a new regime in Sacramento, where he'll help back up Darren Collison. Not bad.
Sessions adds a little size in the backcourt for the playoff-bound Wizards, and becomes the primary backup to John Wall. Increased minutes could see steadier production from the vet, who averaged 12.3 points in 26.7 minutes last season in Charlotte and Milwaukee.
Though the Wizards could miss Miller's veteran leadership, they add a reliable player who has had success as a backup and could be rejuvenated by his new situation. It's unlikely this trade moves the needle significantly for Washington, but it adds an affordable piece that could make the Wizards a little better short-term.
