No. When Peyton Manning was released by the Colts, he was fine after neck surgery.
2012 - 4659 yards, 37 TDs, 11 INTs
2013 - 5477 yards, 55 TDs, 10 INTs
2014 - 4727 yards, 39 TDs, 15 INTs
2015 - 2249 yards, 9 TDs, 17 INTs
So 3 complete seasons later, age and injuries caught up to Peyton at the age of 39. I'll take a chance with Luck. Peyton only struggled in his final season. He was old though. Makes sense. To me, Luck's shoulder isn't a big concern. Again, Peyton Manning's neck is a bigger issue than Luck's shoulder. Peyton was one good hit away from retiring back in 2012.
