Is Dwayne Casey missed?

I'm a Bulls fan looking for some perspective on Dwayne Casey.  I seem to remember John Hollinger writing last year that Casey did not deserve to be fired as he was getting more out of the team than could have been expected.  Casey's name is now being included on the list of candidates for the still open Bulls job.  Is he someone we should want coaching the youngest team in the NBA?  Would he be able to work with a team made of mostly players who need an up tempo system?  Can he actually coach offense?
