A quarterback with some starting experience could be a nice addition
Other than Boyle participating at minicamp, one of the most experienced players in attendance was Bryce Perkins. He is a former undrafted free agent coming out of the 2020 NFL draft that spent his entire career with the LA Rams. He possesses great size and athleticism for the position, but he has not been able to climb the depth chart.
Except for injuries, Perkins has been the steady third string signal caller on the Rams roster. When injuries started to arise, the club decided to add Baker Mayfield to the team and start him for an extended period. This is make it or break it time for Perkins and his young career.
It is possible that he could revert to either the USFL or XFL to try and gain some quality reps to his resume. Perkins has started a game for the Rams in the past, but that was not the best start the league has ever seen. He has only been able to complete about 55% of his passes in the NFL and has only thrown one touchdown.
Pittsburgh would not be signing Perkins to be a challenger for a top backup spot for the black and gold. That expectation is not fair to him, but he could provide something to try and squeak onto the roster as the third arm. He could battle Tanner Morgan for that spot. Worst comes to worst, he could just be a fourth camp arm for the roster.
