Completely agree Dudd and looks like me and you both are saying same things on the BB boards.
I think the engine will be the honest downfall. If the AI is not perfect the weight and such of the players taking bad angles and such will completely break the game.
Football is a complex sport and having a perfect working AI for all 22 players is a tough feat to under take. I don't think the BB team has enough knowledge to succeed in this area.
The tackle engine will bring huge leaps to sports gaming but the AI in the game will ultimately make BB a failure.
