A lot of issues,unrealistic fans,bad team ai and the other team ALWAYS gets a touchdown in just seconds of having the ball which is outright unrealistic.From their own end zone to a touchdown in about 20 seconds and just in 2 plays.
A problem I keep on getting is that once I score,after the kick,the opposing team in seconds just get a touchdown.I don't know if it's just me,but that's been happening to me a ton.
