How good is Devin Harris?

I see Devin Harris in the same situation as Tony Parker a few years back. He had the speed but wasn't able to finish in transition and didn't have the jumper. He's still feeling his way around the team and figuring out where his place is in the offense. The reason why he hasn't blossom yet is because he has always been the 4th option on the team, which means his shot attempts will be limited. Less attempts allows less room for error. Harris is not a pure distributor even though Dallas is trying to mode him into one. He's more of a scoring combo point guard like Damon Stoudemire or a Tony Parker so unless one of the big 3 (Terry, Howard, Notwitzki) gets injured or traded, his role will remain limited. Afterall, there is only one ball to go around so not everyone is going to get enough opportunities to shine. This is the NBA so many players may have to take a backseat and pay their dues for a couple of years before they get to enter the spotlight.
