I do agree that he has gotten less aggressive as a manger (ie "stale"), and that's what I love(d) about LaRussa- the squeeze plays, the aggressive baserunning, and etc. The only player that really does much running is Albert Pujols it seems. And that's being very generous to say that he does "much" running.
I don't see the Cardinals making a lot of changes with their coaching staff. I would be willing to part with McGwire- I can't tell much difference between the hitting this year and last year good or bad. I don't know that changing coaches is a solution anyway- I think the solution is to get a couple of better players, namely an outfielder with some power- I'm not sold on Jon Jay, and a shortstop that can play good defense and get on base at the very least. A shortstop with power would be a bonus in my book. I thought Freese did OK at third when he was healthy, and I'm willing to give him another look. I'd also be OK with getting a couple of middle infielders that are high quality defensively and are good hitters and moving Skip Shumaker back to the outfield.
The bottom line is the Cardinals won 86 games this year, and aside from a couple of years in the late 90's and 2007, the Cardinals have always at least been in contention for the playoffs under LaRussa, and he has won a World Series and gotten them to the World Series another time. I can't complain about that at all. I would much rather get rid of the GM before I got rid of LaRussa.
