The Philadelphia Eagles have been one of the most disappointing teams in the NFL this season, and Carson Wentz has been a central figure in much of the criticism that has been levied against them.

On the season overall, Wentz has thrown for 2,274 yards, 16 touchdowns and four interceptions while completing 61.2 percent of his passes and posting a passer rating of 91.4.

Not terrible numbers, but not what you would expect from a former MVP candidate, either.

Of course, Wentz has a couple of rather significant injuries in his rearview mirror, as he tore his ACL during the second half of 2017 and missed a good chunk of last year due to a back issue.

But the fourth-year quarterback was expected to have a bounceback season in 2019, and it hasn't happened.

To be fair to Wentz, the Eagles have dealt with a whole lot of injury issues this year.

Wide receiver DeSean Jackson played in just two games before going down with a core muscle injury that ultimately required surgery and ended his season, and fellow wide out Alshon Jeffery has been in and out of the lineup as a result of various ailments.

Still, people expected more out of Wentz this season, and there is no question that his performance has been questionable regardless of the fact that he hasn't had a full set of weapons.

At the very least, Wentz has taken good care of the football, as he hasn't thrown a pick since Week 7. However, his accuracy has left much to be desired, which had historically been the biggest issue with Wentz.

Over his first two seasons, the 26-year-old completed 62.4 and 60.2 percent of his throws, respectively. In 11 games last year, Wentz showed improvement in that area, logging a completion percentage of 69.6 percent, but in 2019, he has regressed.

Obviously, it's not so cut and dry, as the Eagles' receivers have not been great, but at the same time, it's the quarterback's job to put the ball where it needs to be, and Wentz has a history of misfiring even with strong offensive talent surrounding him.

Let's face it: many people expected Philadelphia to contend for a Super Bowl this year, and Wentz's return was a big reason for that, so while Philly's struggles certainly aren't all his fault, he does deserve some blame.

It has to be a bit discouraging for the Eagles that Wentz seems to have taken a step back, and I don't even think it's just because of the torn ACL. Remember: Wentz returned from that injury last year and looked pretty good.

This season, he looks significantly worse than he did in 2018.

It is definitely not easy to keep fighting off injuries, but at this point, you have to wonder if Wentz will ever meet the lofty expectations that many had for him following his MVP-caliber campaign in 2017.

Based on his performance thus far in 2019, I would give Wentz a C grade. He hasn't been good, but he hasn't been terrible, either. He has just been very average, and average is not what the Eagles were hoping for going into this season.
