p.s. he's actually got one of the highest volumes of movies I give a 7 or higher. although he's got a smaller part in Kill Bill Vol 2/Menace II Society, especially Kill Bill Vol2 as I might not even count that as a Sam Jackson movie. still, even if I remove that, he's still going pretty strong and even if I removed Menace that still puts at least 6 movies which still puts him more than most bigger names for me to where I would expect he would be in the higher tier in terms of movies he appeared in that I gave a 7 or higher.
