Harrison says Manning is ranked this low because of his play during the last 5 or 6 weeks of last season. Manning was having another great season until suffering a torn right quad that really hurt his play down the final stretch of the season.

Manning started off the season looking like his usual self. He was scoring 3 or 4 touchdowns per game, but it at all fell apart in the second half of the season. Some of that was due to his torn quad, but Manning looked off before that.

I look at the week 11 game against the St. Louis Rams as the turning point in 2014. From that game(week 11) onto the end of the season Manning totaled 10 touchdowns and 8 interceptions. He had 29 touchdowns and 7 interceptions in weeks 1 through 10.

I do not really disagree where Manning is ranked on this list. He is still a really good quarterback, but he is 39 years old. His body will break down quicker, and he is more prone to injuries now. It will be up to new Head Coach Gary Kubiak to run a more balanced offense to keep Manning's legs, arm, and overall body fresh into December and January.

Let's take a look at the entire top ten.

It's not surprise that Aaron Rodgers is the top guy. He has taken over the reigns are the best overall quarterback in the league for a few years now.

Seeing Ben Roethlisberger and Drew Brees that high is a little surprising to me. Brees has had a few down seasons in a row, and Big Ben isn't a top three quarterback in my mind.

Tony Romo is coming off a great 2014 season, and I would ranked him ahead of Big Ben and Brees. I was also a little surprised to see Luck that low. I figured he would be a top 4 quarterback.

I don't know what to think with Russell Wilson. Is he a top quarterback, or a just a good one who benefits from a strong run game and a top defense? My opinion on him changes often.

The real shocker on this list is Alex Smith at 10. He's an alright quarterback, but you're telling me he's better than Tannehill, Stafford, Ryan, Newton etc?

Do you guys agree with this ranking? Should Manning be ranked higher or lower, or do you think Harrison is spot on?
