Cleveland Browns wide receiver Antonio Callaway has been hoping that 2019 would be a breakout year for him, but whether or not he actually gets the opportunity to make that happen remains to be seen.

Thus far, it's not looking good.

According to Scott Patsko of The Cleveland Plain Dealer, Callaway has been stuck on the second unit throughout the early goings of training camp, with Odell Beckham Jr., Jarvis Landry and Rashard Higgins getting all of the first-team reps.

What's more surprising than that is the fact that even when Beckham sat out team drills on Monday, it was Derrick Willies and Jaelen Strong, not Callaway, who saw some action with the first team.

While Higgins beating out Callaway for the No. 3 receiver role would not be shocking, the fact that Willies and Strong may be ahead of him on the depth chart is puzzling.

Callaway is coming off of a rookie campaign in which he played all 16 games and hauled in 43 receptions for 586 yards and five touchdowns, solid numbers for a first-year wide out.

The 22-year-old, who played his collegiate football at the University of Florida, was originally selected by the Browns in the fourth round (105th pick overall) of the 2018 NFL Draft.

As for Willies and Strong?

Willies went undrafted last year and logged just three catches for 61 yards during the 2018 campaign, and Strong has logged 31 receptions for 330 yards total over his first three seasons, which came with the Houston Texans and Jacksonville Jaguars.

It makes you wonder what Callaway may have done (or not done) to get in the doghouse.
