As an AI language model, I do not have access to up-to-date financial information on Cooper Rush. However, I can provide general information on his estimated earnings based on various factors such as his position, experience level, and contractual agreements.

Cooper Rush is a quarterback in the National Football League (NFL). He played college football at Central Michigan University from 2013-2016 before being signed by the Dallas Cowboys as an undrafted free agent in 2017. Since then, he has primarily been a backup quarterback for the team.

Typically, NFL players’ salaries are determined by their experience level and position on the field. According to Spotrac.com, which tracks NFL player contracts and salaries, the average salary of a Backup Quarterback in 2021 was $2.12 million per year with a median salary of $855K.

Specifically for Cooper Rush’s situation: after signing with Dallas Cowboys as an undrafted free agent back in 2017, he joined them’s practice squad—a unit comprised of lower-tier talent that suits up but does not play games—for two seasons.
Then in April of 2020 he returned to sign a one-year contract worth $680k with Dallas Cowboys again (Spotrac).

However approximately estimating how much Cooper Rush makes is rather difficult since many factors come into play considering NFL Players’ total earnings – signing bonuses paid out upon contract agreement or renewals/ extensions extra cash for successful completion of personal achievements like rushing yards etc.
Hopefully this gives helpful insights into what might determine Coopper rush’s possible earnings at any given point throughout his career.

Cooper Rush is a backup quarterback in the NFL. Typically speaking, backup quarterbacks earn less than starting quarterbacks due to their lack of playing time. The average salary for a backup quarterback in 2021 was $2.12 million per year with a median salary of $855K according to Spotrac.com.

However, there are many variables that contribute to an NFL player’s total earnings beyond just their experience level and position. For example, signing bonuses paid out upon contract agreement or renewals/extensions can significantly increase a player’s annual income.

Unfortunately, we cannot confirm if Cooper Rush received any signing bonuses when he signed with the Dallas Cowboys as an undrafted free agent in 2017 or when he returned to sign a one-year contract worth $680k with them again in April of 2020 (as reported by Spotrac).

Other factors that may influence Cooper Rush’s potential earnings include personal achievements like passing yards or touchdowns thrown during games and endorsement deals outside of football related sponsorships.

It should be noted that while our estimates for Cooper Rush’s earnings may vary depending on these variables and other circumstances surrounding his career trajectory thus far – it’s certain those numbers will continue fluctuating throughout his future years within the National Football League elite athletes community.

In conclusion: while we cannot determine precisely how much money Cooper Rush makes currently or has made over the course of previous seasons since specific details regarding contracts/earnings are private between players’ agents/the teams’ management; generally speaking – backups have lower salaries compared to starters but it also varies from team-to-team & difference positions/staff requirements too – which means Journeymen like him might make somewhere between six-figure sums annually and beyond depending on various factors based on their individual contribution to the team.
