“For me, it was like, the fact that I’m not healthy, I don’t feel that twitch or that gear that I felt like I need to have, but obviously I’m out here trying to do everything I can to be on the field,” Greenlaw explained on Terron Armstead’s “The Set” podcast. “It makes it tough when you pay a guy $11 million and he’s only on the field 50 percent of the time. It made it tough for me. It made it to the point where it kind of makes you not happy. Now I’ve got to slowly come in and take reps from somebody else, which the linebackers were playing really, really good at the time, so now I’m just taking reps from this guy. And now it’s like, OK, we’re splitting reps, how are we going to do it? One week it’s this, one week it’s that, and it’s like, I’ve never been in that position before. Yeah, I just wasn’t happy. That’s really what it boiled down to at the end of the day. Everything works out for a reason. I don’t regret none of it. I’m thankful for it all, for Sean ( Payton) and everybody that accepted me into that organization, teammates and all. But, yeah, I’m excited to be a Niner.”
