You are right it does show that pesky bias, unfortunately for you it shows your bias considering the numbers you provided for Kap is for only 7 games started where for Cam it is over a 16 game season. If you break it down on a per game basis:
Cam
253 passing yards/game, 1.3 TD/game, 1.24 TD:Int ratio, 84.5 passer rating
26 rushing yards/game, 0.88 TD/game
Kap
259 passing yards/game, 1.4 TD/game, 3.33 TD:Int ratio, 98.3 passer rating
59 rushing yards/game, .71 TD/game
Stats can be fun when you put them in their full context.
Edit - I also want to point out I am a fan of Cam, so this post wasn't a knock on Cam but to point out how Guano left out an important piece of his puzzle which was games started.
Did you say leave out important stats? Well you forgot to take his rushing TDs from 5 to 3 on the year so you really need to do the math better and that drops Kap to a .42 rushing TDs per game. Also when we take a bigger sample size from the other years which I didn't include for the full effect of Newton's #s being superior to Kaps
2013 Cam had a not so great year but put up a 61.7 comp %, 3379 passing yards for 211 ypg, with 24TD/13 picks to Kap's 58.4 comp %, 3197 for an under 200 ypg 21TD/11 picks.
Oh but let's not forget their 3 year careers:
Cam 11,299 passing yards/ Kap 5,046....more than doubled
Cam 64 passing TDs/Kap 31....more than doubled
Kap didn't start one year because he couldn't beat out the great Alex Smith is your excuse probably. I wonder whose fault that is?
So let's look at one more key stat that you failed on:
Cam 2032 rushing yards with 28 rushing TDs...pretty productive
Kap 937 rushing yards with a whopping 9 TDs...can you say TRIPLE the TDs lol
You are right. Stats can be fun. But be sure to include the key points left out like career production
