I said it was a bad trade, and absolutely no one has denied it. The reason why this has turned into an examination of Arroyo's career is because of the over-valuing of his skills to prove a point that doesn't exist. Arroyo is what he is. Not near Josh Beckett, not a 4.50 ERA, 200 IP pitcher in the AL.
It was a hypothetical scenario. I think it was clear enough when reading that part of the post.
As to the "facts" about him sucking in the AL (which was never the basis of the argument, but rather the fact that he'd be an average pitcher, and i have stated so numerous times), his 2007 and 2008 peripherals (which you are conveniently ignoring) specifically that 1.4 WHIP, and 4.57 and 4.50 ERA moved from the NL Central to the AL East suggest, with let's say, a modest downgrade in performance, an ERA nearing five, and with said ERA nearing five, less turns through the rotation and less IP. It is what it is. You can try to downgrade the NL to AL argument all you want, but like Jacko, you were comfortable using it when critizing the Penny and Smoltz signings. Can't have it both ways.
