21st to 7th — The Dolphins were one of the best examples of the “bend but don’t break” defense in 2012. They ranked 21st in yards allowed per game (356.8) but were seventh (19.8) in points allowed. Only the New York Giants (31st to 12th), Atlanta Falcons (24th to fifth) and New England Patriots (25th to ninth) had a higher jump in the NFL team rankings between yards allowed and points allowed.
2-14 — The Browns’ struggles in Week 1 over the past eight years are well documented, and the Dolphins haven’t been much better. The Dolphins are 2-6 the past eight seasons in openers, making the Browns and Dolphins a combined 2-14 in that span.
0-6 — The Browns are 0-6 since 1991 in head coaching debuts. Bill Belichick, Chris Palmer, Butch Davis, Romeo Crennel, Eric Mangini and Pat Shurmur all lost their first game. The last Browns coach to start 1-0? Bud Carson, in 1989, with a 51-0 win over the Pittsburgh Steelers.
4 — Only four points have separated the Browns and Dolphins in their past two meetings, both wins for the Browns. In December 2010, Browns kicker Phil Dawson broke a 10-10 tie with a game-winning field goal as time expired that was set up by a Mike Adams interception late in the game. In September 2011, Colt McCoy led the offense on a 13-play, 80-yard drive and hit Mohamed Massaquoi from 14-yards out with 43 seconds left en route to a 17-16 win at home.
44.4 — Ryan Tannehill was one of the NFL’s most accurate quarterbacks last season when throwing the deep ball. On passes of 20 yards or more, Tannehill completed 44.4 percent of those attempts. According to ESPN.com, only Robert Griffin III (47.1 percent) and Peyton Manning (45.9) were better.
