I didn't really think of an OLB in round 1 as a dig at Worilds. I just think he and Woodley fit the same position and neither is a ROLB. You do need a pass rush on 3rd downs and being able to rotate in Mingo and even Gholston could help us on the most critical down in football. The Giants SuperBowl a few years back showed the value of rotating pass rushers. Guys just can't rush all the time without wearing down. But you can keep the pressure going if you rotate.
I see Mingo as a situational pass rusher for a couple years in a best case scenario. I'm not 100% sold on him either.
