My bad, I thought Lee was dealt AFTER the Haren.
They weren't thinking about the 2011 rotation, they were thinking about improving the team back in July. Remember Javy had a great June (3.23 ERA and 0.97 WHIP) and July (3.34 ERA and 1.11 WHIP), and no one expected to blow out like he did. Plus Haren has a career 4.07 ERA and 1.30 WHIP in the 2nd half, add the AL East factor to that and you have a problem.
With CC, Hughes, Pettite, Vasquez and Burnett, we all thought Lee or Haren would have been a luxury.
I would love to have Haren now, but getting Haren back then, means they wouldn't have tried to get Lee this off-season.
