Why are you not doing yards per completion and TD/INT%. That is the most fair way to do it. Otherwise obviously the person who plays the most will look better at first glance.
Career against AFCE
| Games | YPC | TD% | INT% | |
|---|---|---|---|---|
| Andrew Luck | 6 | 11.9 | 4.3 | 4.7 |
| Ryan Tannehill | 24 | 10.8 | 3.4 | 2.8 |

When looked at it this way, Luck is clearly better than Tannehill. He clearly passes for more TD and yards per attempt. He only throws more interceptions per a against the AFCE. Which is pretty much what I already knew.
Found an error in the total TDs he's thrown against the AFCE, it's actually 11. 2012: Jets - 0, Pats - 2, Bills - 1. 2014: Pats - 2, 2015: Bills - 2, Jets - 1, Pats - 3.
