Stanley did have a rubber arm, no doubt. I don't think he threw that hard, though.
Anyway, the modern trend is that guys throw a lot harder and throw less innings.
Has anyone ever had a better doubleheader than Nate Colbert did for the Padres on August 1, 1972?
Probably not.
Game 1 4 for 5, 3 runs, 2 HR, 5 RBI
Game 2 3 for 4 + a walk, 4 runs, 3 HR, 8 RBI
Total 7 for 10 + a walk, 7 runs, 5 HR, 13 RBI
The fact is if Bloom signed Gausman we'd be liking it right now.
If he signed E-Rod or Stroman the moaning and groaning would be brutal and we'd be talking about how much of our payroll was tied up in useless junk.
