I'm going to try and put things in perspective and make a little sense out of Thibodeaux vs Walker comparison, attitudes be damned. For beginners, it's an apples and oranges comparison. Thibodeaux is an OLB Edge rusher; Walker is an interior D lineman.
Georgia ran a 3-4 Defense; DT = Devonte Wyatt, NT - Jordan Davis, DE - Travon Walker. Nakobe Dean was a OLB and the designated edge rusher. Walker was a hand in the dirt interior DL, 3 technique in the Georgia system.

Oregon also ran a 3-4 Defense; DT - Hudson-Ware, NT - Aumavae, DE - Dorlus, Kayvon Thibideaux was the Joker, OLB designated pass rusher. Kayvon did not play with his hand in the dirt, he played standing up fromthe 5 or 7 technique.

Interior DL do not usually produce BIG defensive numbers. However Walker's numbers for 3-4 DE are very respectable, much more in-line with something you would see from a 4-3 DE. In all fairness, Walker playing DE in Georgia's 3-4 compromised and did a disservice to his production numbers. In much the same way Wisconsin 3-4 D masked JJ Watt's abilities. Highly probable Wade Phillips could do for Walker what he did for Watt. It should also be noted that Thibodeaux lined up outside of the OT almost twice as much as Walker. When Walker did line up outside of the OT it was on his shoulder, 5 technique, hardly ever in a 7 technique. Expecting Walker to have Thibodeaux production is not a fair comparison and a disingenuous argument. Would Thibodeaux had the same or better production if most of his snaps were as an interior DL? Also of note Walker is bigger and faster than Thibodeaux.
Walker accumulated seven quarterback pressures in the national championship against an Alabama offensive line that is always brimming with talent, and many feel he was playing out of position for most of the year, indicating he could be an even better professional than he was a college player.
