They can't afford to just have their subs let their lead dissipate all the time. This team needs a little balance and is too top heavy (1-6) in talent, but nobody else is doing much. Instead of stuffing the starting line up, maybe it's best to balance it out a little. My proposition would be to move Thompson to the bench with Barnes. Move Green to the starting line up. This would ensure that both groups get ample firepower. Unless the Warriors can sign more talent on that bench, then they are always going to have problems with them.

My line up

Curry- Douglas (Hope they sign another)
Iguodala- Thompson
Green- Barnes
Lee- Speights (hope they sign another big)
Bogut- Oneal
