NOTE: Don't freak if you've seen this before. I started the topic on NetSports and I'm copying and pasting the crap over here too. It's a relevant topic that needs to be discussed among Sox fans and I'm too lazy to come up with more original stuff.
Bronson Arroyo has done a fantastic job for cheap money this season. With time, he could become a very good #3 or 4 starter on a championship caliber team; and that may happen as quickly as this season.
Derek Lowe has been awful, but he has the tenure and the price tag. Sox Brass has a somewhat rightful love affair with BK Kim's potential. These two could spell disaster for Arroyo as a starter and that should not happen.
He has also been very effective working deeper into games as well. For pitches 61-75, 76-90 and 91-105, he has an OPS against of .633, .692 and .409 respectively. His OPS splits per every three innings (1-3, 4-6, 7-9) are .780, .682 and .701. Clearly, the arm strength and stamina are both there for him to be effective deeper into games as well.
He has not been as effective at Fenway, but I think that is about timing. Most of his early starts when he was struggling came at Fenway and his later, better starts have been on the road. Plus, half the team can't hit on the road and the other half crush at Fenway, so he doesn't need to be as perfect at Fenway. Although, consistency would be nice.
Some 2004 Splits
Starter: 4.04 ERA

Home: 5.27 ERA
Monthly Splits
April: 5.79
May: 4.44
June: 4.18
July: 1.20 (as of 7/18)
Once BK comes back, Derek Lowe should not maintain his rotation spot; Bronson Arroyo should.
