Yeah because bills teams have done so well over the last 20 years on offense.
The offense he runs is concept based. if ran correctly there is always someone open. Not only is there someone open but it also gives the offense an opportunity to dictate coverage. Is Allen capable of running it? He seems to grasp the concepts, but he also tends to look off the easier completion for the bigger gain. Also do the qb and receivers see coverage the same since its all option based routes.
