if anyone wants to play around with the data, you can find it here:
it will be fascinating to see this data after a couple of years, particularly to see how much slower players get as they age, especially when they drop off a cliff. the data only goes back to 2015, so it's hard to really say how fast pedey used to be, but it's clear that he hasn't been particularly fast in recent memory, with top sprint speeds of 26.7, 26.3 and 26.2 the last 3 years.
it's pretty amazing how much slower pujols (23.0 ft/s) is than the rest of the league, save a small handful of really slow catchers. it's also amazing how much worse he's gotten in only a few short years, trending to the tune of 24.4, 23.7, and 23.0. to put that in perpective, papi was 24.4 and 24.5 in his last 2 years.
in regards to devers, his chubby face has clearly resulted in skewed perception of his skillset. you see him and *think* he's a fat masher that is a statue at 3b and clogs up the bases. in reality, it seems like he has above average speed (league average is ~27.0 ft/s). what's funny is that these misconceptions work the other way, too. i've heard more than a few announcers describe JBJ as fast (or very fast) when, in reality, he's a few ticks above average (27.4 ft/s this year). this is probably because his jumps in center field create the illusion that he's faster than he really is, but it's still interesting nonetheless.
