Why this game is intriguing: A week ago, this would've seemed like a matchup between two of the NFL's most hapless teams. Yet the Bills' demonstrative win over the Chiefs made us feel guilty for wanting to write them off after the opener. The biggest development: Mario Williams and that defensive front began to look nasty and create turnovers. If Mario and Co. can shut down Browns back Trent Richardson, Buffalo can improve to 2-1, allowing some hype to rebuild.
What to watch: The Browns don't have much reason for optimism, but they do have some points of pride. They are hard-nosed up front on both sides of the ball; facing the NFL's leading rusher (C.J. Spiller) will challenge the defense. Cleveland might try to knock Spiller around early. Will that change the third-year man's desire to go hard? On the other side, it's always worth checking on the progress made by quarterback Brandon Weeden.
