I found this interesting. The Rams use motion as much as anyone and used it 91% of the time against the Lions. Minnesota is also in the upper half of teams that use motion. The Lions struggle a bit against motion. Tampa is near the bottom of the league in motion. Look at some of the top teams on that list. The Lions struggled against the Ravens, Seahawks, Packers and Chargers who are all top 10 in motion. They did well against Carolina, Tampa, Broncos and even the Saints to some degree who use less motion.
