Upon Further Review: Browns Week 2

An examination of four hot issues from the Cleveland Browns' 14-6 loss at the Baltimore Ravens:

Another starting quarterback? Brandon Weeden left in the fourth quarter with an injured thumb on his throwing hand and didn't return. Wearing a brace on his hand, Weeden told reporters after the game he wasn't sure whether he could play Sunday at the Minnesota Vikings. If he can't, Jason Campbell would become the 19th starting quarterback for the Browns since they returned to the NFL in 1999. Here's the list of Browns quarterbacks who have made at least one start: Tim Couch, Ty Detmer, Doug Pederson, Spergon Wynn, Kelly Holcomb, Jeff Garcia, Luke McCown, Trent Dilfer, Charlie Frye, Derek Anderson, Brady Quinn, Ken Dorsey, Bruce Gradkowski, Jake Delhomme, Colt McCoy, Seneca Wallace, Thad Lewis and Weeden.

Failing on third downs: The Browns' defense has improved in most areas except one -- getting offenses off the field. The Ravens converted 8 of 16 third downs on Sunday, including 7-of-11 (63 percent) in the second half. This is becoming a disturbing trend for Cleveland. For the season, the Browns have allowed teams to make first downs on half of their third-down chances. Cornerback Joe Haden gave up his share of completions to Torrey Smith on Sunday, but he's not the biggest problem. The Ravens picked on Chris Owens and Buster Skrine after halftime. Last season, the Browns ranked 16th in third-down defense.

No big plays: The Browns struck downfield with a 53-yard pass to tight end Jordan Cameron on their first offensive play. They didn't complete one past 22 yards on their final 32 passes. This was against a Ravens secondary that gave up nine passes of 23 yards or longer in the season opener. It was a tough day overall for Weeden, whose 26.7 Total QBR gave him his 10th QBR below 30.0 since the start of last season, the most in the league. His QBR of 20.3 this season is third worst in the NFL.

Running in circles: The big storyline last week was getting running back Trent Richardson more involved in the offense. Now, the focus has to be on making him more efficient. The Browns gave the ball to Richardson 18 times, five more than last week, but the results were the same. He averaged 3.2 yards per carry and didn't break a run longer than 9 yards against the Ravens. For the season, Richardson ranks 22nd in the NFL in rushing. Among the top 25 rushers, his 3.4 yards per carry is tied for fourth worst.
