It's also disingenuous to compare grass to baseball infield dirt (you didn't play both sports, so you wouldn't know. Fun fact. The fastest MPH ever in baseball were achieved on grass by outfielders). It's also disingenuous to not consider that top speeds aren't reached until about 60m running in a straight line. Many of the top speeds in the NFL were reached via 50, 60, 70 yard plays. Even in my OP example, the top NFL speed was reached at 99 feet. Trout's 21.50mph speed came via a stolen base, which actually isn't 90 feet and more like 78 feet (12 foot lead off). So again, do you deny the fastest baseball players aren't as fast as the fastest NFL players? Deion Sanders is still one of the top 10 fastest NFL players to live, and Billy Hamilton beat his home-to-third time.
Seems like you're Philo'ing just to Philo.
