Dragic/Bledsoe work pretty well together and a lot of teams run 2 point guard lineups at points in the game with success. I think that is actually the most fun way to build a team is to have an identity you want them to have and pick players around that rather than just getting the highest rated player available. I like playing unique lineups like creating a team with 2 centers, a 2 PG team or a team with only 6'9 athletic guys that just switch everything on defense and play uptempo.
