For you, colonels ... anything.
The story of the first game is told in the first half. The home team was extremely hot (66%) and the away team was extremely cold (29%). That resulted in a lopsided 39-17 halftime score. If these teams played 100 times you wouldn't expect a halftime score that lopsided very often, but this in itself is hardly crazy, unprecedented or something that should never happen.
In the second half that margin continued to widen, in large part because the away team's reserves played a lot more than normal, and on this team there is a monumental difference between the starters and backups (the starters were recruited by a human, the backups by a sim).
In the second game, the sim team was at home, so of course we know already that's a significant factor in the equation. Instead of one team being very hot and the other being very cold, there was a more normal result, with both teams shooting 41-44%. The sim team was able to play their starters for normal minutes, so that makes a real difference, too.
So I'd say that the biggest factor was simply a very hot first half for Lane paired with a very cold first half for Clark in the initial game. That led to Clark's really crappy reserves playing the majority of the 2nd half, widening the gap even further. Then factor in the home/road advantage.
Mistakes that the Lane coach made:
-Not running uptempo. As mentioned, there was a huge disparity between the sim team's starters and reserves. The sim team also ran a press. So the Lane coach missed a great opportunity to make sure that the sim's reserves would be on the court as much as possible.
-Running a +1 defense. Clark-Atl takes a decent amount of 3p's (as most sims do), but they are simply an awful 3pt shooting team at 29% for the season (vs. a 245 sos). Their starting guards and sf have pe ratings of 54, 47 and 36. You practically want to beg that team to shoot more threes. I would've backed off a little and dared them to shoot more 3p's, probably a -1 or -2.
If he does these two things, he wins the second game, no question in my mind. And then this thread doesn't exist, and the world is a better place.
