Like you said the average bettor doesn't always look at all the stats that they should. I expect this to be a pretty close game. San Diego will probably stick to the same plan they had in the 1st 2 meetings in trying to run the ball, work the clock, and convert the 3rd downs that they should. Since they have been pretty successful at this tactic all year I expect them to at least have some success meaning the Broncos will have less chances to get the offense going keeping it a semi-low scoring game such as high 20's maybe low 30's.
I am expecting a high scoring game and possibly a blowout if the Broncos offense comes out executing like the greatest offense in NFL history that they are are.
As long as we don't beat ourselves, we win this game by 2-3 scores.
