The ACT of coming on the field immediately before the snap is deceptive to the defense though. It doesn't give them a fair chance to adjust.

Taking too long in the huddle(if you have been subbed for) is deemed deceptive by the NFHS isn't it?



This is just the opposite of too many men on the field .
