According to Jordan Ranaan of NJ.com, Cruz said he didn't like how the Jaguars secondary was targeting Beckham.
"I was a little unhappy last week. I felt some of those [defensive backs] were gunning for him. It was sad to see that go down because I couldn't help him. I couldn't go out there on the field and run routes with him. I couldn't take some of the pressure off him and things like that."
And although Cruz never mentioned free safety Sergio Brown by name, it's obvious to anyone watching the game he's talking primarily, if not solely, about him.
"From the line you could see it right when you're running the route and you're running a vertical route. You take a peek at the safety and see where he is before you look at the ball and you just see him head down trying to spear you. You can see that from a mile away."
During the game, you could see that Brown and the rest of the Jaguars secondary had gotten in Beckham's head, who had zero receptions on five targets.
On the first throw, Eli Manning targeted Beckham along the left sideline who short-armed it due to Brown coming in at an angle that would've rocked the Giants receiver.
And then on Beckham's last target of the game.
UPDATE: After hearing Cruz's comments, Jaguars free safety Sergio Brown responded to the allegations he was "gunning" for Beckham. (Thanks to Mike DiRocco of ESPN.)
"No. That's just football. It's a preseason game. That's how you play football in the NFL. It's not practice. It's live, so if they throw the ball up, you've got to be prepared to catch it or protect yourself. No gunning."
Jaguars cornerback Davon House defended Brown and attributed Beckham's frustration with not registering a single catch.
"I don't know if he was frustrated from what Sergio did or what he thinks Sergio might have done or if he was just frustrated because he wasn't getting enough balls. I don't know. It's a better question for Odell to answer and their offense."
All in all, a fun preseason so far.
