I dont mind a hurry up offense when needed, but lord almighty can we just go back to where a team sends the play call in with a substitute, gives it to the qb, and then he tells the players in the huddle? The hand signals, posterboard pictures, and the like where everybody has to look to the sideline seems stupid. Heck, we already rotate players in and out every single play and 90% of the time we still get down to 10 seconds or less on the play clock. Just go back to a system that ensured everybody was on the same page.
