This team has a ton of holes, even if Marcin Gortat (likely) and Trevor Ariza (increasingly unlikely) return next season. While lots of us harbor dreams of swinging a trade for Kevin Love (not happening) or poaching Greg Monroe from Detroit (ditto), there are better ways to improve this team by simply signing unrestricted free agents. Here's a handful of guys I think can help this team.
Note: I'm only including totally available players that I think would actually be happy here, not guys at the end of their careers who might be chasing rings, or guys with player options.
Backup Point Guards - Assuming we let go of Miller, which we should consider.
Jordan Farmar - Hurt last year in LA, but played well when healthy.
Mario Chalmers - Proven winner being phased out in Miami.
Ramon Sessions - Solid scorer who lives at FT line.
Patrick Mills - Proven winner who may want a bigger role than John Wall's caddy.
Combo Guards - Guys who can play alongside John or Brad.
Jerryd Bayless - Often hurt but can score and run point for stretches.
Rodney Stuckey - Power combo guard and noted Wizards killer.
Jodie Meeks - Volume 3pt shooter who will feast on open looks from Wall.
4th/5th Bigs - Bigs who provide a specific skill currently lacking.
Kris Humphries - Solid rebounder with little offensive game.
Anthony Tolliver - Can stretch floor, but more of a tweener.
DeJuan Blair - Can we finally sign this guy? Damn.
Jordan Hill - Probably out of our price range.
Jason Smith - Injured last year, but can stretch floor.
Greg Stiemsma - Good shot blocker in limited minutes.
Charlie Villanueva - Reclamation project who can shoot and score.
