I think it is interesting to note (also it may point in favor to what I have mentioned) that many of the most renowned/successful coaches were not big hitters. Brad Gilbert, Paul Annacone, Magnus Norman, (I'd consider him successful now), Larry Stefanki, etc. I think Jimbo was a bit of a gamble, we all know his personality on court when he was young, so who knows if that affected his relationship with Andy. Plus, I thought game wise it was a completely shitty direction for Andy to head towards. Sure, I'm positive that much of it just had to do with getting some fire in his camp and revitalizing his spirits a bit, but certainly game wise, Roddick wants to be on the opposite spectrum of Connors..
I always felt Connors would have been a better coach to the other Andy, given 'fire' is what he has perennially required. Funnily enough, Lendl should have fit the bill all the same but the results aren't there to see. When you look at the past, was firing Mulligun even the right thing to do for Murray camp?
