The only point I am trying to make is that we are not qualified, from this perspective to determine if an umpire if failing. If it was a safe/out call then fine, you can see that. With calling balls and strikes, you can't tell from TV. Everybody who watches baseball thinks they are a qualified evaluator of umpires, most are not. You are a teacher also, what do you think when parents, or anyone outside of your profession tries to evaluate your skills? Using your teaching analogy, would you be OK with two kids in the same class having completely different grading scales? What we're seeing is two different strike zones. What is being called a strike for the Cards is not being called a strike for the Cubs.
