Hard to make conclusions based on a scrimmage, especially with my game shape being all over the place, so I can't assume this would happen in every game I used this lineup, but I don't think I'll be using LCD during the season.
(85520109)My SG played 48 minutes, perhaps because his backup was a scrub. My SF played 44, his backup has terrible GS due to an injury. And my PF played 42, there's a dropoff to his backup too, but probably not as much as with the other two.
Like I said, scant evidence of anything, but its possible in a big game, where minutes don't matter and you want your best players on court as long as possible, that LCD might be the way to go.
