With four games -- and three wins -- in 18 days, the Ravens earned this mini bye week, but they did little to alleviate some of the concerns they had entering Thursday night's game. No one outwardly expressed feeling the emotion, but I sensed relief in the Ravens locker room after the 23-16 win over the Cleveland Browns, as if 53 men had just collectively exhaled. It wasn't just because they survived a last-second shot at the end zone from quarterback Brandon Weeden or that they struggled all night to shake the Browns on a wet, sloppy night at M&T Bank Stadium. The Ravens had just played four games in 18 days -- three of them came in primetime -- and though they finished the first quarter of the season 3-1, there was little celebration as the weary players changed into street clothes and headed out to start their mini bye week. Maybe after they catch up on some sleep and spend time with friends and family, they will appreciate what they have done in these past 18 days -- beating two divisional foes and winning a thriller against their non-divisional rivals from New England. "As far as it being a relief, I don't think so. We know where we should be, and that's really where our focus is at," Ravens inside linebacker Jameel McClain said. "But there aren't a lot of teams being asked to play all of those games in 18 days, and we came out the way we came out. It wasn't exactly the way we wanted, but it's still a good way to come out. Now it's time to finish the next quarter of the season." Up next in the gauntlet are Kansas City, Dallas, Houston, and after a bye week, Cleveland again. Dallas and Houston are playoff contenders and Kansas City is better than its 1-2 record indicates. And while the Ravens should feel good about what they have accomplished so far heading into that next quarter, it's understandable why they don't want to dwell on it. Four weeks into the season, some difficult questions still linger with this team. The pass rush, which pummeled Weeden early in this game, again became a virtual non-factor for much of the second half. The offensive line, which had played pretty well through three weeks, was flagged for a handful of penalties, allowed four sacks and opened up few running lanes for Ray Rice. The secondary, which got a pick-six from Cary Williams, allowed 320 yards to Weeden, making him look like a 28-year-old veteran instead of a 28-year-old rookie. The Ravens rank near the bottom of the NFL in pass defense and nine former Pro Bowl quarterbacks still remain on their schedule. That's not to say it should be gloom and doom in Baltimore. The Ravens are who we thought they were: a championship contender. And despite their early blemishes, they appear to be one of the few legitimate threats to win the AFC. Joe Flacco is among the league leaders in passing yards, Rice is still getting his, and the defense has come up with big plays when the team needed them these past two weeks. The Ravens know they have a lot work to do. But first, let's hope they savor this hard-earned weekend off.
