Right is wrong: I'm not sure if I've ever seen one side of a line play so poorly as right guard Oniel Cousins and right tackle Mitchell Schwartz did Sunday. Cousins has an excuse because he's a third-stringer making his second career start at guard. Schwartz, a second-round pick from a year ago, does not. Sure, Schwartz had a tough assignment in Pro Bowl end Cameron Wake, but he looked like an overmatched rookie in what was the worst effort of his 17-game career. Schwartz allowed three sacks and countless quarterback hits. Cousins was flagged four times, including a fourth-quarter holding penalty that brought back a touchdown. Shawn Lauvao needs to get healthy quickly.
Trent Richardson carried the ball just 13 times for 47 yards against the Dolphins.
Questionable play calling: Did offensive coordinator Norv Turner forget about Trent Richardson being a 300-carry running back? Richardson ran the ball on four of the game's first six plays. He then had nine carries in the last 66 plays. Instead of putting the ball in the hands of their best offensive player, the Browns chose to throw the ball 53 times in a game that the Browns were trailing by a field goal heading into the fourth quarter. In order for Richardson to be a 300-carry back, he needs to average 19 carries per game. He had a grand total of 13 in the season opener. Richardson had only four games with fewer carries last season.
Tale of third downs: Some will point to turnovers as the reason the Browns lost, but Miami got only one field goal out of Brandon Weeden's three interceptions. This game was decided on third downs. While the Browns' defense did a commendable job in stopping the run and getting pressure on quarterback Ryan Tannehill, Cleveland couldn't get the Dolphins off the field. Miami converted eight of 16 third downs, which is quite an improvement for a Dolphins offense that ranked 16th on third-down conversions last season (38 percent). Tannehill was 9-of-13 for 82 yards on third downs, an average of 9.1 yards per completion. The Browns, meanwhile, couldn't stay on the field. Cleveland was a woeful 1-for-14 on third downs.
Stumbling in season openers: The Browns are 1-14 in season openers since returning to the NFL in 1999. Eight of the losses, including Sunday, have been by double digits. The only season-opening victory was in 2004 against the Baltimore Ravens, and the Browns finished 4-12 that season. No coach in the expansion era Browns has won his first game. The six coaches -- Chris Palmer, Butch Davis, Romeo Crennel, Eric Mangini, Pat Shurmur and Rob Chudzinski -- have lost their first game by an average of 16.1 points. Surprisingly, Davis, Crennel and Shurmur all won their second game as Browns coach. Chudzinski draws the defending Super Bowl champion Ravens in Week 2.
