" He’s tough. He’s physical. He’s built that way. There’s not a lot of leaky yardage. He’s a knockback tackler. They stop where he hits them. There’s an intensity to how he plays. He’s one of those players where if you put the film on and didn’t say anything, at some point early you would ask, ‘Who is this guy?’"Payton added that he thinks Greenlaw’s physicality was "one of his greatest strengths.""He plays the position in such a way where you can’t help but notice it on film. His pad level, his strength, his lower body strength. It’s impressive. I’m glad we have him," he added.BENGALS STAR TREY HENDRICKSON SET TO END LENGTHY TRAINING CAMP HOLDOUT WITHOUT NEW CONTRACT IN PLACE: REPORTDenver finished 10-7 last season and had a top 10 defense.
