The NFL preseason is one of the most exciting periods on the sports calender.
Unfortunately, a few players didn't exactly shine in their first August tune-up.
From highly touted rookies, to big-name quarterbacks to entire teams, there were several duds during the opening preseason games. Here are the biggest disappointments, thus far.
The most famous backup quarterback on the planet, Tim Tebow put up some Tebow-esque numbers in his first game with Gang Green.
Tebow played the second quarter and most of the third, but he was only able to lead the Jets to three points. He completed 50 percent of his passes (4-for-8) for 27 yards and threw one interception on his way to a 18.2 passer rating. He also had four carries for 34 yards.
Of course, Tebow has never been one to impress statistically, and it would have been unrealistic to expect him to put up big numbers in his first game with his new team. Still, Tebow will have a bright spotlight on him all season, and if he doesn't show some improvement in his mechanics and decision-making, he will be behind Mark Sanchez on the depth chart all season.
Brandon Weeden—QB, Cleveland Browns
Brandon Weeden was the 22nd pick in the 2012 draft, but the 28-year-old rookie was unimpressive in his NFL debut.
The former Oklahoma State QB completed just 3-of-9 passes for 62 yards while throwing an interception and losing a fumble. Although it's tough to be too hard on a rookie in his first NFL game, it's not a good sign when you get outplayed by Colt McCoy, Seneca Wallace and Thaddeus Lewis.
Weeden will get his chances in Cleveland, but the fans will run out of patience if he can't improve soon.
The Chicago Bears
I'm just going to put the whole Chicago Bears team on this list after they lost to Denver 31-3 in its first preseason game.
The Bears offense was simply terrible, as they mustered just eight first downs (three of which came on penalties) and failed to convert all 11 of their third-down attempts. They also racked up just 132 yards, turned the ball over three times and didn't score until a Robbie Gould field goal in the fourth quarter.
Their defense wasn't much better, allowing 338 yards and 25 first downs. The Bears will certainly look better in the coming games, but this early result is very discouraging.
