Arizona is a good team but they are not the best team in the league.
That is correct. Right now that would be The BoSox for all of MLB and a tie bewtween the Marlins, Diamondbacks and Cubs in the NL alone.
"Best Team" can change on a daily basis. It's not a permanent fact.
If I had to win game 7 of the World Series, I`m starting Jake Peavy before I start Brandon Webb.
1. That would be a bad call.
2. Brandon Webb is not the only good pitcher on the D-Backs staff. Apart from Peavy, what other "great" pitcher does does San Diego have? Pitching in SD starts and stops with Peavy. Arizona has Webb AND Haren AND up and coming stars in Micah Owings (who can also hit) and Max Scherzer who will be a Cy Young contender in his own right in years to come.
