John Harbaugh is trying out Jim Harbaugh’s old QB Shea Patterson

Shea Patterson is getting a workout with the Baltimore Ravens.

The Baltimore Ravens not only have one of the league’s best players at their disposal in electric quarterback Lamar Jackson, but backups Robert Griffin III and Trace McSorley are two of the best in the business at what they do.

Even with that security, John Harbaugh is looking to potentially add a fourth quarterback, and he’s calling on one of Michigan head coach and younger brother Jim Harbaugh’s former signal-callers.

As the Ravens decide to fool around with the back end of their practice squad, the elder Harbaugh is working out former Wolverine gunslinger Shea Patterson, who went undrafted after two seasons in Ann Arbor.

Shea Patterson was consistently inconsistent during his time at Michigan

After showing some promising flashes at Ole Miss, Patterson, a former 5-star recruit, transferred to Michigan for the 2018 and ’19 seasons.

While throwing 45 touchdowns against 15 interceptions sounds like good production, those numbers belie the fact Patterson’s arm talent and accuracy were not what Michigan thought they were getting. He played so poorly against elite Big Ten teams that there was legitimate consideration being given to starting backup Dylan McCaffrey.

Patterson did get a Senior Bowl invite, but nearly everyone who watched practice saw that he was clearly the worst of the six quarterbacks who were invited to the event due to his issues with throwing the ball deep downfield and even taking the snap from center. He went undrafted and didn’t even sign a UDFA contract. The Kansas City Chiefs brought him in on a tryout basis, but they waved him soon after.

Patterson wasn’t great at Ole Miss, and he didn’t perform as expected at Michigan. Naturally, signing him to back up Lamar Jackson should fix all of his problems, right?
