Pomeroy blogged about this month back (I just noticed).

It's a pay site. I trust this excerpt falls within fair use rules.
2-Foul Participation is simply the percentage of time that a starter with two fouls in the first half has been allowed to play.
If a starter picks up a foul with ten minutes left in the first half and plays one of those remaining minutes, then he’s participated in 10% of the minutes he could have. Add up the possible minutes for all starters and the minutes on the floor and you get the team’s number for the whole season. That figure was around 20% for all of big-time college basketball last season, a number that has been dropping steadily since 2010, the first season for which we have complete play-by-play data.
Coaches are gradually getting more conservative about playing guys with foul trouble in the first half. Even with foul rates declining to historic lows last season, coaches were less willing to play a guy after he picked up his second foul.
