So from what little I know of the history there were some serious personal issues going on in the team that led to ~7 of the 11-12 folk on Quake eventually leaving.

Sandy has gone into it on various podcasts and mediums. It's pretty clear he doesn't consider Carmack responsible but rather someone he refuses to name (but is quite obviously Tim Willits) that caused pretty much all the problems.

My read is Carmack is saying he is sorry he lacked the awareness and experience to manage the people stuff.

He lost his dream team, I'm sure it's something he has thought about a lot.
