Regardless of Joe Dumars thinking that basketball is best played by "putting the best players on the floor vs the other team's best players", I don't think we should have a set starting lineup. Look at our roster, it's meant to be versatile at almost every position. Yeah, PG and C are set positions pretty much, but everything in between is still up for discussion. When we go up vs a team like Miami, isn't it better to have a player like Stuckey driving against the weak Chris Bosh and whoever they play at center (I don't think that Miami will play Oden much until late postseason so he doesn't get injured)? It would make no sense to let KCP go against Wade. Why not play KCP when we go up vs Atlanta and they have Al Horford and Paul Millsap down low, but Krover up top?
When we need more athleticism to go against a fast team like Golden State or even Miami, why not start Josh Smith or Tony Mitchell? When we want to beat em in the post why not use Monroe?
To me, it just seems silly to have the same players start every single day when we have arguably one of the top versatile teams in the league.
