The move makes sense. Rush, a former undrafted free agent, spent the last three seasons playing for Jason Garrett in Dallas. Garrett is now the Giants offensive coordinator.
Rush played in only five games during his time in Dallas. He went 1-for-3 for 2 yards in 2017, his only regular-season NFL passes. He became expendable in Dallas when the Cowboys signed Andy Dalton.
RJ Ochoa of SB Nation’s Blogging the Boys, which covers the Cowboys, told us this about Rush:
“The rookie version of Cooper Rush that the Cowboys found in 2017 was very nice. After going undrafted he battled his way onto the roster with an impressive preseason and put the team in a pickle. To that point the Cowboys were doing everything that they could to keep a low-level backup quarterback on the roster and nobody knew why (his name was Kellen Moore). Rush’s stout exhibition period forced them to carry three quarterbacks for fear of losing him and eventually he topped Moore to the point that Kellen went into coaching. Overall though through three seasons he showed regression when he did play (which admittedly was generally during the preseason) and does not carry enough experience to be trusted with the most important job on the team if push came to shove.”
The Giants have Colt McCoy, Alex Tanney and undrafted free agent Case Cookus as backups to Daniel Jones. The Rush signing would seem to put Tanney’s roster spot in jeopardy.
The giants waived wide receiver Reggie White Jr. to make room on the 90-man roster for Rush.
