I've been in a situation where I had a manager who was a nice guy. Everyone took advantage of him and none of the people under him really grew unless they changed teams. My career stagnated for a long time there and it significantly sapped my confidence and professionalism. I jumped out prematurely and made some bad career moves after that.

My general advice is to follow your gut. If you feel like your manager is actually hurting your long term career prospects, then you should switch teams or company. If not, and it's just a passing feeling, you can stay. A decent check for the former is to see how much growth you've had under this manager and then take a call.
