This current lineup isn't realistic at the beginning of the season.
The lineup to start should have been:
White
Murray
DeRozan
Lyles(?) (I don't remember if he started the season with us. If not, Carroll)
Aldridge
Mills
Walker
Gay
Poeltl
9 man rotation to start
Then, as the season progresses, you include Keldon. In my ideal World Keldon would be starting over Murray to finish the season. So it leaves:
White
Keldon
DeRozan
Lyles
Aldridge
Mills
Murray
Walker
Gay
Poeltl
I think the team would have started slow, with chemistry issues, but as the season developed they would have started to get their together. By the second half of the season, with Keldon already in the lineup, the team would have found its groove and became a much better team.
Probably still no more than 8th seed, with a few games over .500.
