Ryan was a freak of nature.
Yes, he could throw 100+. WHEN HE WANTED TO. But he didn't try to throw every pitch that hard. That's the difference between today's "pitchers" and the guys from years ago.
I recall a game against the Red Sox where he threw something like 230 pitches over 13 innings (in the same game, Luis Tiant was a complete game loser in a 15 inning Angel win).
