Four Dallas Cowboys roster candidates are starting OTAs.  

OTAs are kicking off on May 21 for the Dallas Cowboys, who will hold practices for three days before taking a six-day break

They return for more work May 29-31 and have minicamps starting June 4.  

There won't be a shortage of plots to follow when the Cowboys play, including the continuing drama surrounding Dak Prescott and CeeDee Lamb's contracts.  

Even though every single one of those players is crucial, there are still many more to come, including some exciting roster battles.  

Despite not making many moves in free agency, a few returning players are still on the roster bubble for Dallas.  

Here are four players who will be competing for a spot on the 53-man roster and know they have their work cut out for them.  

Brooks wasn't vital to the offense, but he made the most of every opportunity. 

Brooks played just 77 snaps on offense and had six passes thrown his way. He caught every one of them, totaling 64 yards. More importantly, four of his six receptions went for first downs.
