During the entirety of the four years of Luck’s rookie contract, Grigson drafted a total of three offensive linemen before the seventh round:
- Hugh Thornton (cut before his rookie deal expired and never played again in the NFL)
- Khaled Holmes (cut before his rookie deal expired and never played again in the NFL)
- Jack Mewhort (never played again in the NFL after his rookie deal expired)
You can argue that the style in which Andrew Luck plays makes him more likely to be injured, and that is true.
You can argue that a player can be injured at any point in time, whether he has a good or bad offensive line, and that is true.
But what you can’t argue is that Ryan Grigson’s spending of cap dollars came to a head in 2015, producing subpar talent along the offensive line (one of the cheapest in the NFL).
And Grigson’s decisions produced measurable results in terms of volume of hits and sacks on Andrew Luck in that 2015 season (via Pro Football Focus):
2012: 38.1% pressure rate, 8% sack + hit rate, 41 sacks
2013: 37.5% pressure rate, 6% sack + hit rate, 32 sacks
2014: 36.2% pressure rate, 5% sack + hit rate, 27 sacks
2015: 40.2% pressure rate, 14% sack + hit rate, 34 sacks (extrapolated to a 16-game season)*
*Played only 7 games due to injury
Luck played in 2016, but was once again a man running for his life, as the stats clearly show:
2016: 44.3% pressure rate, 9% sack + hit rate, 44 sacks (extrapolated to a 16-game season)
Luck was pressured even more frequently than he was in 2015, and was sacked the most often of his career. A hit early in the season to his throwing shoulder resulted in a torn labrum, which he played through all season long. He also sustained injuries to his right elbow and thumb, as well as his left ankle and a concussion.
Ryan Grigson was fired after that 2016 season.
All told, under Grigson’s watch, Andrew Luck was pressured on 1,111 drop backs during 70 games, for an average of 16 pressured drop backs per game.
Under Grigson’s watch (2012-2016), Luck was the most pressured and most hit quarterback in the NFL.
