After signing a massive $100 million extension with the Dallas Cowboys over the offseason, wide receiver Amari Cooper has yet to live up to the hefty expectations of his big-money deal. As a matter of fact, a quick look at the numbers seem to show that the 26-year-old has been deteriorating on a per-game basis.

Brian Martin of the The Star provides the details as to the Cowboys wide receiver's seemingly inexplicable free-fall in terms of his snap count:

Week 1 – 94.4%

Week 2 – 91.5%

Week 3 – 79.3%

Week 4 – 76.8%

Week 5 – 63.6%

As you can see, No. 19 has seen a dramatic dip in his playing time since the season opener against the Los Angeles Rams. His offensive snaps have dropped by nearly 31% and for someone who’s being paid like he is that’s completely unacceptable. There’s been no announcement made as to why Cooper’s role is being slowly diminished, but there has to be some underlying cause.

One thing is clear here: The Cowboys have not been utilizing Cooper as expected. After all, he's one of the highest-paid players in the league right now, so for him to serve as nothing more than a role player for his team is just baffling.

He does not seem to be going through any injury at the moment, which makes things even more mysterious. It would have been more understandable if the Cowboys announced that Cooper was dealing with a lingering injury, but that does not seem to be the case at the moment.

Dak Prescott's season-ending injury will also have a long-term effect on Cooper, but for Dallas' sake, we're all hoping that their star WR is able to pick himself up sooner rather than later. The Cowboys are 2-3 in the NFC East, which, amazingly, is good enough for the division lead.
