"There's not a doubt in my mind that I'll be back out there playing on the field," Cruz said. "Zero doubts in my mind that I'll be playing in that first game."
Cruz, of course, suffered a horrendous season-ending torn patellar tendon during a Week 6 loss to the Philadelphia Eagles last season.
Cruz said he hopes to begin cutting "soon," but that he has to continue to be patient in his rehab efforts.
"I didn't know how much patience that I really had," Cruz said. "I had to be pretty patient. I was forced to be.
"I'm at a place where I want to push it, I want to go faster. I want to start cutting, I want to do different things. I've gotta be patient, I've gotta understand that it takes time and it takes discipline in order to continue to rehabilitate yourself."
Cruz jokingly said he "might jump off a building" if he has to keep asking questions about looking forward to teaming up with Odell Beckham.
"I do feel like I can continue to be that same guy that I was before and it's gonna heal to a hundred percent. It's just a matter of being patient and making sure it's fully healed before I try and do anything," Cruz said. "I just want to be a guy that catches everything Eli Manning throws my way and scores as many touchdowns as possible."
