That 2011 draft (where Cam was the #1 pick) was amazing... other than those 3 awful QBs, all the other top 12 picks were Pro Bowlers (Cam, Von, Dareus, AJ Green, PPete, Julio, Aldon & Tyron Smith).
Nick Fairley went 13th, then 3 more Pro Bowlers (Quinn, Mike Pouncey, Kerrigan), then the Pats took Nate Solder 17.
That draft also featured many other Pro Bowlers including Cameron Jordan & Jordan Cameron, & Anthony & Richard Sherman (both Shermans were 5th round picks). Besides Cam, 2 other QBs from that draft have made the Pro Bowl - Andy Dalton (35th pick) & Tyrod Taylor (180th pick).
Bottom line? None really. Fields & Lance will be as good as they're going to be no matter where they're drafted. Some drafts are much better than other drafts & some picks are good, some picks work out poorly due to circumstances, & some picks are just lolbad.
