According to your logic, when Baltimore had 10 less rushing TDs in 2013 compared to 2012, that means Joe Flacco should have had 10 more TDs? Why did he have 3 fewer with 84 more pass attempts? When NE had 6 less rushing TDs in 2013 compared to 2012, that means Brady should have 6 more TD passes? Why did he have 9 less TDs with only 9 fewer pass attempts? Luck had 23 TDs in 2012 when the team rushed for 11 TDS. The team had 4 more rushing TDs in 2013 (which according to you should result in fewer TD passes for Luck) yet Luck had 45 less pass attempts but still had 23 TDs.
