I think your conclusion is questionable. Obviously the Lions are much improved and dangerous, but their win wasn't "epic fashion" considering the Bills did it one week ago. Saying they beat 10 win teams is true, but not indicative of how those teams are this year or last year for that matter. I'm a Chiefs fan, but they won like 4 of their games on luck. Had them pegged for 6-10 this year. Take away their best defensive and offensive playmakers, and they're a 4 win team.
