Oliver Perez: He's almost too easy, because of the surface comparisons to Johnson. Perez has an electric arm, but he's wildly inconsistent, especially with his command. The raw talent, however, is there for him to be of the game's best starting pitchers for a long time to come. Perez is vastly more accomplished than Johnson was at the same age, though his career has been more scattered than the Unit's was. With 56 wins under his belt at the age of 27, there is plenty of time for Perez to find himself and have a fantastic career.GAH???!!!
If Oliver Perez pitches until he is 45 years old, he will need to win 13 games every season for the next 18 years. He has only ever won more than 13 games once in his life.
He says that Perez is "vastly more accomplished" at the age of 27 than Randy Johnson. I suppose that is correct, in-so-far as Perez has run the gamut of his entire career at this point. He's had 9 seasons as a starter, Johnson only had 4. The Unit was a late bloomer while Perez is already a has-been. In his first four 4 seasons as a starting pitcher Johnson racked up 44 wins. Ollie has 56 wins...in 9 seasons as a starting pitcher.
Ollie is averaging 5.67 innings per appearance (since you can get a win as a reliever, and Perez doesn't look to be seeing a rotation any time soon, I won't break it down by starts) while the Big Unit has been a workhorse his whole career. Over his 22 seasons he is averaging 6.75 innings per appearance. This gives Ollie a full inning less per appearance to get those 244 wins he needs to hit 300.
Even if Perez finds his mojo and becomes dominant, he would need to win 20 games per season for 12 seasons and win a couple games at 40 to hit 300. Really? This is the guy leading your list?
Oliver Perez will win 300 games around the same year Todd Van Poppel wins a Cy Young.
