Things are heating up around Oklahoma QB Kyler Murray. First, he was rumored to be the potential No. 1 overall pick in the 2019 NFL Draft.

Then, the negativity started pouring out. First, former NFL GM and current NFL Network analyst Charley Casserly said teams told him the Heisman Trophy winner was a terrible interview. Then, Dan Patrick revealed that one of his sources thought Murray inflated his height at the NFL Combine.

Now, Murray’s agent, Erik Burkhardt, has gone scorched earth against Casserly. In an interview with Pro Football Talk, he ripped the reports coming out about his client:

“So what do I think about an agenda-driven ‘analyst’ who’s never once even talked to Kyler or any of his coaches or teammates?” Burkhardt said. “I think it’s disgusting and embarrassing and Casserly should be ashamed of himself.

“Further, my business partners and I personally represent coaches and executives who sat in on eight of Kyler’s 10 formal combine interviews. I spoke directly to each of them, as well as executives from the other two teams and many others who I don’t represent but were present, and all of them were extremely positive about his entire interviews, with each citing specific examples as to why.”

Burkhardt was far from through with his takedown of Casserly, though, throwing shade at the former GM’s decision to draft Heath Shuler:

“The bottom line here is that it calls into question the motives of a man to get on national television and cite anonymous sources on things such as ‘leadership’ and ‘study habits’ about somebody he’s never met,” Burkhardt said. “Look, If you don’t like Kyler’s game, it’s cool. If you don’t like his size and want to talk about that, that’s fine, too. If you’re into a Heath Shuler-type looking guy, then hype those guys and say why. But when you slander the character and work ethic of a young man who’s worked his ass off his entire life and done everything right to put himself in his current position, you’d better cite your sources and come with a better record than 18-46 as a G.M. of the Texans, and whose own leadership and accountability has been questioned by his old bosses and colleagues, as well as the greatest coach on the planet.”

Those are some harsh words, and we’ll see what sort of twist this saga takes next. Buckle up, folks, because there are still a few weeks to go before the draft.
