Harbuagh would have done a much better job developing Sanchez than Schitty and Soprano but the trade-off would have been we would not have had an elite defense from 2009-2011. Harbaugh ahd the benefit of falling in on a great D in San Francisco that was loaded with talent.
Sort of like Rex landing on Mangini's D (at least talent-wise?).
