Did we mention that Americans love football? Late April is about as far away from football season as you can get, and fans get restless. (College spring exhibition games happen around the same time, probably for the same reason.)
What’s more, it’s not a peak moment in the American sports calendar. The other major college draw, NCAA basketball, is long done. The only major sport deep into playoffs is hockey, which isn’t huge among Southerners, who make up a huge swath of the NFL’s fan base. It’s still a little early to get excited about anything that happens in Major League Baseball, and the NBA playoffs are just getting started.
