What honestly do you think Protzen and his team would have achieved using these? It could only be much worse. Please think about that one. I won't even mention the lifting and positioning to give you a fighting chance.
Let's just stick with the precision. How would he have coped?
What, you think he's suddenly going to start making crazy, sloppy joints just because the job is bigger, like throwing wild pitches, to continue the sports metaphor?
If you're suggesting he couldn't cope because he's only one man, well, he is only one man.
