This was not how things were supposed to go for Cleveland Browns quarterback Baker Mayfield in his second NFL season.

Mayfield was supposed to stamp his name among the elite signal-callers in the league, posting big numbers and leading the Browns to an AFC North division title.

Obviously, that is not what has happened.

Instead, Mayfield has thrown for 3,109 yards, 15 touchdowns, and 16 interceptions while completing just 59.2 percent of his passes and posting a passer rating of 77.6.

As for Cleveland as a team? It is just 6-7 and only has very slim playoff chances.

That pales in comparison to Mayfield's rookie year, when he threw for a single-season rookie record 27 touchdown passes to go along with 3,725 yards and 14 picks, completing 63.8 percent of his throws and registering a passer rating of 93.7.

And that was with less weapons at Mayfield's disposal.

The Browns went out and added Odell Beckham Jr. this past offseason, giving Mayfield a tandem of Beckham and Jarvis Landry in the aerial attack.

Mayfield was supposed to grow in 2019. Instead, he has regressed, and his rather questionable attitude on top of his lackluster performance does not exactly help matters.

To be fair, Cleveland has a whole lot of problems this season. The defense stinks, the offensive line has been inconsistent and Freddie Kitchens looks in over his head.

But when a team is expected by many to contend for a Super Bowl and ends up disappointing in this fashion, one of the first people to get the blame is going to be the quarterback, especially when they aren't playing particularly well.

Outside of a stretch from Weeks 10 through 12 when Mayfield threw seven touchdowns as opposed to one interception, he has not had an impressive run of play at any point in 2019.

Those three weeks represented his only multi-touchdown efforts of the season, and he has thrown at least as many picks as touchdowns in nine of his 13 games.

We can blame Kitchens all we want, but at some point, Mayfield needs to start making plays, and that is something he has not done consistently this year.

To be fair, the expectations for Mayfield were probably too high to begin with. Sophomore slumps have always been a thing, and teams probably did not take the Browns all that seriously last year when they made their second-half run.

A full offseason to prepare for Mayfield and Co. has certainly played a role in Cleveland's disastrous season, so now, it's up to Mayfield to make adjustments after the rest of the NFL has adjusted to him.

The University of Oklahoma product is still just 24 years old, so he has a long road ahead of him. There is plenty of time for him to improve and leave what has been a miserable 2019 campaign in the distant past.

But when evaluating Mayfield for this season and this season only, it's hard to give him anything above an F grade. He has played well below expectations, and he has done a poor job of leading his team through adversity.

Perhaps Mayfield will be much better in this third season, but his sophomore year has been an unmitigated disaster.
