National Fail League: The biggest flops from Week 1

After several months of anticipation, the first NFL Sunday of the season is in the books. And while plenty of teams had reason to celebrate, there were just as many people around football that would love a mulligan.

By now, you've seen the highlights. But here's where you'll find the lowlights -- one last look back at the week's biggest fails before we turn the page to Week 2.

So without further ado: Welcome to the National Fail League.

ESPN Fantasy App

In gearing up for the new fantasy football season, ESPN relaunched a brand new app to house all of its fantasy sports hubs. But just a few minutes into Week 1, it became clear that the site had a major problem on its hands.

Some four hours later, service was restored -- but not until all of the 1 p.m. ET games had been completed, and the late-afternoon contests were wrapping up.

The outage didn't affect any player's scores, which was encouraging, but the extended absence managed to put a damper on the should-be national holiday that is the return of football.

Cardinals long-snapper Kameron Canaday

Heading into Sunday night, the Cardinals were heavy favorites to take care of the Tom Brady-less Patriots in the desert. But by the early going, it was clear that fill-in quarterback Jimmy Garoppolo was ready to take on one of the presumed Super Bowl favorites.

Despite playing from behind for most of the game, Arizona actually put itself in position to win the game in the closing seconds. Entered Chandler Catanzaro, the team's 25-year-old kicker who entered the game with a career 57-for-64 kicking clip. But a subpar snap messed with Catanzaro's timing, and the second the ball left his foot, it was clear how this one was about to turn out.

The kick soared well left, giving the Patriots a win in the first game of their Brady-less stretch to open the season.

Finally -- finally! -- the Patriots were vulnerable to open a season. With no Tom Brady or Rob Gronkowski in Week 1, the odds were stacked against New England to grab hold of the division from the outset.

But, in typical Patriots fashion, that's exactly what they did.

Not only did they steal a win on the road against Arizona, but every other division rival lost.

So, for Buffalo, New York and Miami, the four-game window of battling against a diminished Pats squad is already a quarter of the way through. And once Brady returns, it's fair to expect the team to suit up for the following 12 games with a very well inflated chip on their shoulder -- we remember what happened the last time New England played like they had something to prove.

Devonta Freeman fantasy owners

After a breakout campaign in 2015, Devonta Freeman was one of the top running backs to go off draft boards this season. But in Week 1, it was owners of his backup, Tevin Coleman, that had the last laugh.

Against the Buccaneers, Freeman was handed the ball 11 times for a total of 20 yards, and added another 20 yards through the air on four catches without a score. Coleman, meanwhile, racked up five catches for a whopping 95 yards, getting more touches than many expected heading into Sunday.

Freeman owners: It's not quite time to panic just yet. But this wasn't a great sign.

Terrance Williams

Starting rookie Dak Prescott under center for Week 1, the Cowboys actually outplayed the division rival Giants for much of Sunday afternoon's matchup. Prescott performed better than anyone could've expected, and Dallas charged down the field in the final minute of the fourth quarter in position to win.

Without any timeouts left, Prescott completed a pass to Terrence Williams near the sideline -- placing the Cowboys within field goal range for kicking robot Dan Bailey. Williams, though, inexplicably turned away from the sideline and was tackled in bounds, keeping the clock moving.

Prescott wasn't able to line the offense up and kill the clock in time, and it resulted in a crushing home loss to New York.
