There is an infinite amount of debate about the most effective aspect of the hurry up offense that will be a part of the San Francisco 49ers strategy in 2016. New head coach Chip Kelly's main talking point is that the more offensive plays a team runs, the more chance you have of gaining yards. There are arguments that the tempo makes it more difficult for the opposing team to defend, it takes more endurance during the game as well as a significant amount of additional preparation during the week before a match up. It limits substitutions on the defense and a good offense can take advantage of those mismatches.
