There is a ton of "if" in that statement.
Not trying to turn it into a "RAWRZ NOT AS GOOD AS THE PHILZ" pissing contest, but as A Phillies fan, i can see that as a "potential" top 5 rotation (assuming CC Sabathia doesnt come to the NL)
But as I said, there is a ton of "if" in that - something to look forward to, thats for sure.
Oswalt is not long for baseball.
Stras, Zimm, 1 more elite pitcher, is that as good as Halliday, Hamels, Lee - the answer is yes, especially at the Nats pitchers will improve with age and the Phils pitchers will decline.
