1. Keenan McCardell, Vikings wide receivers coach
Fred Taylor let everyone know in a post on social media that he would be interested in becoming the Jaguars' running backs coach but he isn't the only former player they should consider adding to their coaching staff. Keenan McCardell has made a name for himself coaching the Minnesota Vikings wide receivers.
You could make the case that Justin Jefferson would thrive regardless of how his coach is, and you would be right. That said, he's not the only Vikings receiver McCardell has mentored. The former Jaguar also had a positive impact on K.J. Osborn and has played a role in Jordan Addison's development. This shouldn't be a surprise to the Jaguars, who know how good a coach McCardell is.
Leaving aside that McCardell gave Jacksonville a dynamic receiving duo alongside Jimmy Smith, he also did a good job coaching their receivers in the late 2010s. Under his wing, D.J. Chark became a Pro Bowl receiver in his sophomore campaign. Dede Westbrook, for his part, had 66-catch seasons in back-to-back years. McCardell was also able to get the most out of Chris Conley, Keelan Colen, Colin Johnson, and even Laviska Shenault Jr.
When Urban Meyer became the head coach of the Jaguars in 2021, he let McCardell go, but that was a bad decision. He had already proven himself and he continue to thrive in Minnesota. Pete Prisco of CBS Sports believes McCardell would make for a great offensive coordinator, arguing that he'll be hard on his players.
Of course, that's just one man's opinion but you will be hard press to find someone who has something bad to say about McCardell. Add the fact that he's a familiar face and he would be a great choice for offensive coordinator if they felt inclined to part ways with Press Taylor.
