How is assuring the correct outcome on the field "awful?" Have you ever watched an NFL game? Most challenges take 5 minutes and 75% of them confirm the call on the field, and they most definitely do not "assure" a correct outcome. Very few NFL challenges take 5 minutes. And if it means the correct call is on the field, whether it confirms or overturns the refs call, then as a football fan I'm ok with that. They have so few plays to review now in MLB and they've already fucked up a few.
