Mike Pettine alluded to it in his end-of-season press conference, and a look at how this year's playoffs unfolded only confirmed it.
The Browns need to improve not only because owner Jimmy Haslam, general manager Ray Farmer, Pettine and the rest of the team's contributing members aren't satisfied with a 7-9 finish, but also because the competition promises to be dramatically elevated in 2015.
"The lessons we learned this past year do us no good if we don't correct those mistakes, that we don't make them again, and just knowing and planting the seed that in 2015 it's going to be a bigger challenge for us, just for the sheer fact of the schedule – the teams that we play," Pettine said. "I know our strength of schedule will be much more difficult. We know we have to be that much better moving into next year."
It starts, of course, with the Browns' own division, which sent three teams to the AFC playoffs. On top of that, the Browns are swapping out the cross-divisional matchups they had with the AFC and NFC South for games with the AFC and NFC West.
While the South divisions produced just two teams with winning records during the 2013 regular season, the West accounted for five, including NFC champion Seattle. The Browns will play on the Seahawks' home field, a place at which Seattle's lost just twice in the past two seasons.
Nine of the Browns' 16 regular season games in 2015 will be against teams that made the 2014 playoffs. Three of the other games will be against teams that finished 8-8 or better.
The Browns' 2015 opponents combined to go 107-100-1 in 2014. For comparison's sake, the teams they played this past season finished 90-117-1.
Does this mean Cleveland's schedule will ultimately live up to its billing? Of course not, but the Browns are carrying the mindset that nothing will come easy in 2015.
How this schedule breaks down will come to light in April, when the full slate is released. Here's how each team fared in 2014 and how they've done over the past five years.
