There probably aren't many people that have much confidence that the Cleveland Browns will sport a top-flight offense this season. Not among that group of people lacking confidence, though: wide receiver Dwayne Bowe.

“I’m very, very confident,” Bowe said, via Cleveland.com. “We have a talented core, our group. All it takes is time. We’ll let the doubters doubt. When we get on this field and work, we know what we’ve got as a team, the chemistry. When Week 1 comes around, we’re going to show a lot of doubters how a high-powered offense really moves.”

The Browns finished last season 27th in points per game, 23rd in yards per game and 24th in Football Outsiders' offensive DVOA. Their only offseason additions of note were Bowe, fellow receiver Brian Hartline, and rookies Cameron Erving and Duke Johnson (they'll also get center Alex Mack back from injury). With Josh McCown starting at quarterback, that does not exactly sound like the recipe for a jump into the top half of the league, let alone a "high-powered" offense. But Bowe isn't worried, not even about McCown's subpar preseason performance.

"Not really,'' he said, when asked if McCown's two picks in the second preseason game were cause for concern. "That's what this is for -- to try to find openings, new plays, new schemes to work on. That's what our coaching staff is doing, trying to see what works and what doesn't work. I think when the season comes around, he'll pick his poison. He'll know where to throw it and where not to throw it. I'm very confident that he'll make the best decision."

The two preseason inteceptions aren't all that troubling in and of themselves, but expecting McCown to suddenly become a passer that takes care of the football is setting yourself up for disappointment. The book on McCown might be that he's a veteran who doesn't make mistakes, but it's far from the actual truth. He was intercepted on 4.3 percent of his passes last season, the second-highest rate among the 36 quarterbacks that threw at least 200 passes in 2014.

That number was also pretty much right in line with his career rate of 4.0 percent (excluding the wildly out of character five-game stretch in Chicago in 2013 that saw him get picked on only 0.4 percent of passes), which would be the highest among the 54 quarterbacks that have thrown at least 1,500 passes since McCown entered the league in 2002. Even if you leave that fluky Chicago stretch in McCown's career totals, his 3.5 percent interception rate is seventh-highest among that 54 quarterback group. He does not protect the football very well at all.

Considering McCown is also 41st in completion percentage, 42nd in yards per attempt and 45th in touchdown rate among that same group, Bowe's proclomation earlier this summer that McCown is "showing all the potential of being a top-five quarterback in the NFL" seems likely to be off the mark. It's good to have confidence in your group, and especially in your quarterback, but the reasons people are skeptical that this will be a good offense are real.

Dwayne Bowe has a lot of confidence in his offense. (USATSI)
