According to Profootballtalk, a rumor is circulating that the NFL may opt to go with 1 ref for placement of the ball on the field while all penalties will be called from the booth. What doesn't make sense to me is how that would work. What if the Bills got hit with a 4th and inches after clearly get the yardage needed for a 1st down, how would Gailey be able to challenge that without a ref on the side line to see him throw the challenge flag? I hope this rumor never turns out to be more than just that, personally I think it's a very bad idea. Your thoughts?
