I love a true 6th man. I had one this year in
Stanley Lamon, and once I could ditch promises and shorten my bench, the season really came into focus. He was always getting minutes, because I had him backing up the weakest stamina player for most of the season; but when I switched to postseason mode, I put him in the second slot at all 5 positions in many games. Clearly you can’t do that with most players, but most players CAN swing between at least a couple positions. So the key to getting them minutes then is 1) getting them in that second slot in multiple positions, and then 2) creating a stamina/minute gap between the starters at those positions. If the starters are relatively close, I will consider setting the one with better stamina to getting tired (setting your backup to getting tired generally doesn’t do much; unless his stamina is *really* low, like in the 40s or 50s, that’s not the reason he’s only getting 12 minutes). This works best if that higher stamina guy also is a good, athletic defender, of course, if he’s a weak defender, more time on the floor for HIM isn’t going to be a net positive.
The reason to shorten your bench like this is to limit exposure to your weaker players, especially freshmen in the postseason, so your experienced players are carrying the load for you. Then those back-bench players are only in when everyone is winded, to maximize the time your best players get at 100%.
