No he doesn't really suck, but he is not as good as everyone is making him out to be. He is definitely not the top QB going into the 2014 season. Lets review shall we?
1) Is his mobility top in the league...... Clearly NO!!! He's probably bottom of the league in this category.
2) Is his arm strength top of the league..... Um not quite!!! Again probably near the bottom of the league.
I will give him that he is the BEST is pre-snap reads and getting his Offense lined up. Probably has the best QB IQ. But he isn't a stand alone in this regard. QB's like Brady, Rogers, Brees have this ability and Luck is up and coming.
Lets review the 2013 schedule: in order: Ravens, Giants, Raiders, Eagles, Cowboys, Jaguars, Colts (they lost), Redskins, Chargers, Chiefs, Patriots (lost), Chiefs, Titans, Chargers(lost), Texans, Raiders.
Anybody who remembers last season would tell you that overall the majority of the teams didn't have a good season. The first 6 games alone had horrible defenses, and yes I say the Superbowl defending Champions because they lost key players from that run to this first game. They were unprepared for Denver.
Lets look at the 2014 schedule: Colts, Chiefs, Seahawks, Cardinals, Jets, 49ers, Chargers, Patriots, Raiders, Rams, Dolphins, Chiefs, Bills, Chargers, Bengals, Raiders. Also a week 4 bye.
Look at that lineup. Good luck going against those top defenses. Only games I see easier for them is Raiders, Dolphins, and the Bills. I will be surprised if the team is better than 9 and 7 this year. I will also go and say the week 4 bye could hinder Peyton's ability to play a full season, just a possibility.
Lastly I will leave it with this. Manning had a great season and probably got lucky with the schedule he had, but if he was such a top notch QB, why didn't he give the Bronco's a chance in the Superbowl? Shouldn't someone highly regarded as him, will his team a chance to come back and win?
