Who will be willing to share PG duties with LeBron and D-Wade in Miami?

It's July 16th, and the Miami Heat still don't have the minimum players required to play a game in the NBA.Heat Nets tickets are already sold out. The 2 through 4 are obviously filled, now the 1 and the shot blocking center role need to be filled for the starting lineup.  Mike Miller signed to be the shooter for the Heat.  Big Z has (unofficially) joined the team to start as the center , and Juwan Howard, Joel Anthony, and Dexter Pittman signed to come off the bench .  Udonis Haslem also resigned to round out the front-court subs.  Maybe the Heat don't sign a 1 ?  LeBron or D-Wade can bring up the ball, they demand the ball a lot anyways.  Wade, LeBron, Bosh, Miller, and Z could be the starting 5. Do the Heat really need Mario Chalmers to start for the team?  Can the Heat find someone better than Chalmers to take less money to take the inbounds pass and quickly dish it to LeBron or Wade ?  I'm sure the Heat will experiment with playing Wade, LeBron, Bosh, Miller, and Big Z , and then experiment with a small roster of Chalmers, Wade, Miller, LeBron, and Bosh.  The possibilities are endless with the combinations of going big or going small after Miami finishes picking the roster , hopefully Erik Spoelstra has Pat Riley's permission to do what he wants with the roster.  No matter who they sign, those Heat Bucks tickets are going to be hard to get next year.

So who can Miami still sign ?  The Heat need two more PGs, preferably players that are sharpshooters from 3, a player like Eddie House.  Eddie would have to play for the minimum salary , but the Heat could offer a chance to play his energy backup PG role for the favorite in the East.  That's if the Heat players don't ask for Rafer Alston back to play for less money and to let him try to rejuvinate his career.  Alston has a badreputation for not playing well if he's not the starter.   Jason Williams is another player with experience on the Heat that could backup Chalmers and bring up the average age on the team.  Both Eddie House and Jason Williams have won championships, which seems to be an crucial trait when teams are looking for 6th man/energy players/x-factors to fill out the roster.
