re: Peregrine falcon, that takes me back to when I was a kid. I didn't know specifically about the 242 mph, but I was fascinated with falconry in general and the Peregrine in particular. 'Course, you know how it is when you're a kid. Fascinations last at most for 6 months before being supplanted by some OTHER fascination.
re: speed. So, it's FUN, it can be PRODUCTIVE, and it is usually an ADVANTAGE in crucial games. I'm down with that. Elite speed is a joy to watch.
When I was a kid, Maury Wills was the guy getting all the attention for his stole base records. But the elite speed on the team belonged to The Three Dog, otherwise known as Dodgers' centerfielder Willie Davis. His nickname came from the number on his back and the fact that he hit so bloomin' many triples. Davis was a sublime joy to watch running the bases. Note to myself based on my recollections: Watching a speed-burner run the bases is a different thing live compared to watching it on TV. Live you can see the entire vista, the outfielders chasing a ball in the gap that's rolling to the fence, multiple baserunners scrambling to take the extra base, and Willie D. absolutely streaking around to third or home. I'm sure I once saw him get an inside-the-park home run on a ball he had no business getting it, though I don't specifically remember any such play. Edited to add, I ran across this article on The Three Dog, you might find it interesting:
If I had a choice between a few elite speed burners mixed in with three plodders and a team with good (but not elite) overall speed and only one plodder, I'd choose the latter every time. But if you're like the M's, it's a given that you have three plodders in the middle of the lineup -- Seager (18 GIDP), Cano (18), Cruz (15)*. So I'll take three speedsters. I DESPISE GIDP's. Every one kills an inning.
* Interestingly, the Mariners had the fourth hightest GIDP total in the AL. Also interestingly, the team that had speedster Mike Trout had the second highest. Speed is great, but you put enough plodders on a team, and they can negate a lot of the speedsters' contributions. Angels' plodders -- Pujols (24), Escobar (21).
