Tenure: Four seasons, 42-85 record
School's last tourney bid: 2004
Coach's last tourney bid: 2010 (Clemson)
Most of the teams on this list haven't amounted to much of anything in a long time.
But DePaul was pretty good less than a decade ago. The Blue Demons had three seasons with at least 20 wins in a span of four years from 2003-07.
Quite the opposite these days, they've lost at least 20 games in three of Oliver Purnell's four years as head coach.
Purnell has a winning percentage of 33.1 at DePaul, but that's artificially inflated by some of the weakest nonconference scheduling in the country.
Against Big East competition, DePaul is 9-63 (12.5 percent) over the past four years—and not one of those wins came against a team that went on to make the NCAA tournament.
The shame of the matter is that Purnell came to DePaul with a great track record of turning programs around.
Radford was hovering around .500 for a few years before Purnell got his first head coaching job in 1988, but the Highlanders were 22-7 three years later.
From there, he moved on to Old Dominion and brought the Monarchs two CAA regular-season titles and an NCAA tournament appearance in just three seasons.
After that, it was on to Dayton to rebuild a program that was 10-47 in the two years before his arrival. The Flyers won at least 21 games in five of the final six years of Purnell's nine seasons with them.
Most recently was his rebuild of Clemson from an ACC bottom-feeder under Larry Shyatt to a team that would win at least 21 games in each of the final four seasons of his seven-year term.
So, what gives? Why can't he fix DePaul? At every other stop on his world tour, Purnell won at least 20 games by his fourth season with the program. Yet, DePaul hasn't even hit a baker's dozen in any of his years there.
He'll get at least one more year to try to make his mark on the Blue Demons, but this will almost certainly be his last season as their head coach if they don't finally show some signs of improvement.
