I've only watched a few games so far and ... wow, the umpires never get any better.
Apparently Jose Canseco tweeted some stuff about how bad they are. Some news outlets jumped on him, only to meet with a bunch of on line comments saying, he may be a jerk but he's right on about this one.
It's got to be tough to be a miked-up coach with all that going on, knowing you have to bite your tongue at the latest outrageous call.
Worse are the commentators, who all have to be approved by LLWS (per the contract with ESPN) and who therefore must keep everything Pollyanna-ish about how wonderful it is to have all-volunteer umps.
The system of staffing doesn't work well. My guess as to why is that it disproportionately attracts the egotistical guy from your local LL who looks upon an invitation to Williamsport as vindication of his own opinion of himself. (I can just hear them at the pregame home plate meeting talking about "MY strike zone blah blah blah." As if anyone wanted them to devise one that differed from the one in the rule book.)
I honestly think I could pull 4 spectators at random out of the stands and they would do a better job.
