Coaching Continuity as a Player

When talking about my football background today, I had something occur to me that never had before.  I only played six years of football--two in high school as my school didn't get football until my junior year and then four years of college.  In those six years, I had a different OL coach every year.  And, due to a coaching change after my freshmen year of college, three different head coaches in only six years of playing.  Just curious to see if anyone else had similar experiences!
