Why Andrew Luck's most impactful year on the NFL was his last year at Stanford (OC)

Lets first flashback to 2010. Luck was coming off a successful redshirt freshman year and help lead Stanford to an Orange Bowl victory along with being the runner-up in the Heisman and a first team All-American.

Had he entered the 2011 NFL draft, he would have very likely been the first player taken and would have changed not only the Carolina Panthers franchise but some other lucky team that year would have got Cam Newton instead of one of the other meaningless QB's taken that draft (Locker, Gabbert, Ponder, etc.).

Even bigger dominoes fall if he wasn't in the 2012 draft however. Without Luck as the sure fire number 1, there's a decent chance the Colts would have kept Manning instead of releasing him and Denver signing. The year of "Suck for Luck" might have happened different considering RG3 wasn't considered a can't miss prospect until well after his Heisman season was over.

With the Colts having a high pick, there's no telling if they would have drafted RG3 or traded down like St. Louis did to stockpile picks. Even if every QB just gets taken one QB spot up from where they were drafted, the Seahawks, Redskins, Browns, Eagles, Dolphins and pretty much every NFL team's future would look different.

Would Denver have the same success with Wilson instead of Manning? Would the fall of Brock been even worse with the Browns? Would the flashes of Foles brilliance be more sustained in Seattle? Would Luck have been able bring the Lombardi trophy to Carolina?

Instead Stanford got a similar season from Luck his junior year (Heisman runner-up, BCS bowl, All-American), and we all got NFL history as we know it.

Edit: formatting, Manning released.
