I didn't know that rule, but you pay a manager and a coaching staff to do so, and they can be rightly criticized for not knowing this; especially when you fired a manager to hire a new one to "take the next step" or however we sold it.
Managers/coaches/leaders are there to give the team the best chance to win and to not screw it up. The fact that La Russa has basically had to apologize a number of times already this year is an issue. One could expect a few issues in terms of learning personnel and the bullpen, etc., but, again, he's being paid a lot of money to maximize our chances to win, and he sure wasn't forced into it.
It's so incredibly disappointing that we had to watch all the crap since 2008 and endure a rebuild to see a team sabotage itself due to overthinking what it needed in leadership and under thinking what it needed in roster construction. I'm still going to watch, but not only do the fans that have stuck around through this deserve a better product to watch, guys like Tim and Abreu and others deserve better for leading the team through the rebuild.
