He was almost universally viewed as having gotten fucked over by Joey Saputo.
What does the rest of the league think of Jason Kreis? Mike Petke?
We can play this game all day - there are only 20 manager positions open in MLS, some of the teams prefer foreign managers, and relative to other leagues in the world, there's very little managerial turnover. The way things are structured, there are always going to be decent managers who are out of work in this league.
To your point, there have only been 3 coaching vacancies in MLS since Petke was fired. One of them he interviewed for but didn't get, and in the other the midseason interim replacement got the job. the 3rd was boy city which had their guy earmarked all along.
Houston fired a coach midseason this year, and the interim guy is still in the position.
So its not like there have been a boatload of opportunities and he's been slighted. He had an interview for the one job he might have been able to get.
