3. Cooper Rush, QB
With the Cowboys nearly $14 million over the cap, chances are that they're going to look at their current contracts for help freeing up space. With that in mind, it wouldn't be shocking if backup quarterback Cooper Rush is a cap casualty.
Rush joined the Cowboys as an undrafted free agent back in 2017, spending his entire career with the franchise aside from a five-month stint with the Giants in 2020. He's led Dallas to a 5-1 record across six starts in 26 appearances, completing 60.6% of passes for 1,619 yards, eight touchdowns, five interceptions, and an 83.6 passer rating.
It's clear that the Cowboys love having Rush as Dak Prescott's backup, but that run could be coming to an ending. According to Spotrac, Dallas can open $2.25 million in cap space if they trade or release the 30-year-old at any point this offseason.
Considering how important every penny is when building a championship contender, Rush could be sent packing if the Cowboys believe the sacrifice is worth it.
