1. Browns rookie quarterback Baker Mayfield passed for 295 yards and two touchdowns in his NFL starting debut, an impressive performance that was blemished by four turnovers (two interceptions, two fumbles). It was the fifth-most passing yards by a No. 1 overall NFL Draft pick in the Super Bowl era in their first-career start.
2. With Mayfield under center, the Browns rolled up almost 500 yards and 42 points, their highest-scoring output since 2007 and fourth-highest since the franchise resumed operations in 1999.
3. The Ravens should put that kind of production to the test with one of the league's best defenses. Baltimore is ranked second in yards-per-game allowed and third in points allowed.
4. Cleveland's defense has proven to be equally as dominant in a different way, as the Browns lead the league with 13 takeaways in four games. To put that figure into context, they had that many in 16 games last season.
5. Carlos Hyde is the only running back in the NFL to have a rushing touchdown in all four games after another solid performance in Oakland. He has 83 carries for 285 yards and five touchdowns on the ground.
6. His understudy, rookie running back Nick Chubb, ran for 105 yards and two touchdowns on just three carries last week, becoming the first Browns rookie to eclipse the 100-yard mark since 2014. His first touchdown — a 63-yard run — was the longest since Lee Suggs' 78-yarder in 2003.
7. Mayfield, the former Oklahoma star and Heisman Trophy winner, will face off against two of his college teammates this weekend in Ravens tight end Mark Andrews and offensive lineman Orlando Brown. The trio was part of a Sooners team that developed into one of college football's top offenses.
8. This will be the second-to-last time the Browns play a Baltimore team led by Ravens general manager Ozzie Newsome, who announced earlier this year he plans to step down from his position following the 2018 season. Newsome, of course, is the Browns all-time leader in receiving yards (7,980) and was inducted into the Browns' Ring of Honor and the Pro Football Hall of Fame. He started his foray into the personnel side of things with Cleveland back in 1991.
9. Cleveland combined for nine turnovers in its two games against the Ravens in 2017, a far cry from the Browns of this year, who have a league-best takeaway differential of 7.
10. The last time the Browns beat a divisional opponent? Cleveland took down the Ravens in Baltimore back on Oct. 11, 2015. The Browns are 0-12-1 against AFC foes since then.
