1) I think I understand why he started Arriola, but I don't agree with it - I wanted Weah from the start. I think think he wanted to have Arriola harass, pressure, and run at Costa Rica to wear them down, then sub Weah for him so he could run at a tired defense. I get the thinking behind it, but again I don't agree with it. I think how we played proved this out because Arriola isn't the best player to have out there to build from the back like we did.
2) Only if we know what the outcome would have been had Arriola started, but that higher power is the only thing to know the result in that alternate universe, so I suppose that's a serious philosophical dilemma.
