Javier Perez has a higher winning percentage that Bob and his roster was a complete mess because of Curtis and past mistakes of Bez/Vanney.
You can argue he got a hell of a lot more out less talented players than Bob is with the highest payroll in the league.
Honestly if we had a proper sporting director I would have given Perez a shot at a rebuild. Tactically he seems to got the mind for it, but would have needed a real hard ass for and assistant.
I would have like to see Perez and MB as assistant, could have been an interesting combo.
