I'm currently a senior in college. The number of lecturers I would consider "good" (or better) at lecturing is small. I've had probably ~30 lecturers at this point. Of those, <=5 are >=good.
And I don't know what your experience has been, but the majority of the good/excellent lecturers I had in college were actually TAs & low end adjunct or associate professors, not the preeminent tenured research professors.
