This is a popular mantra on other boards, especially KUSports.com where posters tend to fly off the handle (myself included in that). I've heard it a lot - it just takes time for a 1st year coach to implement their systems. They always struggle. There is always pain before their is gain.
Is this true? Well it just didn't "feel" right to me. I could name plenty of programs that canned their coaches and say instant improvement the next year. So I did some research on the interwebs. Check out this link:
From 2008 to 2009, 15 of 22 teams that entered the 2009 season with new coaches actually IMPROVED their records. That's 68%. Several stayed the same. Only the minority got worse.
While it's a small (but recent) sample, I think it clearly disproves the myth that coaching transitions take time and require a step back before a leap forward.
