Unless they were "star" players guys from the 2010 draft class would be too expensive (on 2nd contracts) to keep as "depth" anyways. So that point kinda goes away.
There is no way that the 2002 draft is anyhow related to success. Kiesel and Foote are clearly the best players from that class. They are not guys who put a team over the hump and win a championship.
If anything, it was the 03 and o4 drafts that put this team in a position to win SBs. A franchise QB and an elite HOF level talent to build your defense around. You can have all the 2002 type classes you want. I will take top-heavy drafts like 2003 and 2004.
Also the draft is solely about identifying and selecting talent. So Keenan Lewis and Emmanuel Sanders certainly do count. Multiple other NFL teams had a chance to take those two players, and they took other prospects instead. Some turned out ok -- others did not.
As to Jason Worilds -- not my favorite guy at all BUT he posted 25.5 sacks in 5 seasons. Guys drafted +/- a year or so from Worilds outside of the first round as pass rushing OLB:
Akeem Ayers - 13 sacks
Justin Houston - 48.5 sacks
Courtney Upshaw - 3 sacks
Sergio Kindle - 0 sacks
Victor Butler - 11 sacks
Cliff Avril - 52.5 sacks
Phillip Wheeler - 5.5 sacks
Justin Durant - 3.5 sacks
J. Sheard - 23.0 sacks
Sam Acho - 13 sacks
P. McPhee - 17 sacks
L. Houston - 17.5 sacks
O. Schofield - 13.5 sacks
C. Barwin - 38.5 sacks
P. Kruger - 31.5 sacks
Q. Grove - 9.5 sacks
The point is (and I'm sure no one but me cares) we need to be realistic when generating player comparisons and standards for performance. Other than 4 of the players listed, Worilds was better at his primary task - rushing the passer. Now did WOrilds need to be taken in the 2nd round of that draft? That is a question that can never be answered. But he did ultimately perform about as well as a 2nd round pass rusher can be expected to.
The days of pulling league leading sack guys out of the 2nd and 3rd day of the draft are simply over. And yes, you can start listing the exceptions to that. I'm talking general trends. CBs, QBs, LTs, and edge rushers are the new overdrafted positions in the NFL. Used to be WR and TE, and that has fallen off a bit.
