Every team in the league has role players in their starting lineup lol. Just look at the two teams playing in the finals right now...Crowder and Bridges start for the Suns and the Bucks start PJ Tucker and Brooke Lopez. The Jazz finals teams had Russell and Ostertag in the starting lineup, hell even Hornacek would be considered a role player. Jordan's Bulls started players like Ron Harper and Luke Longlely, Bruce Bowen was huge in the starting lineup on Spurs championship teams, Derek Fish started on Lakers championship teams. Even super teams with 3 superstars fill out the rest of the starting 5 with role players. Look at some of the players Lebron won titles with... guys like Shane Batier, Mike Miller, Cladwell-Pope, J.R. Smith, Tristan Thompson, etc.
I could go on and on listing different players but the point is every single team throughout the history of the NBA has had role players and complimentary pieces in their starting lineup, even the championship teams.
