Sando has quarterbacks divided into four tiers: Clearly worth a No. 1 overall pick, Close but not quite, You could make an argument for them, and On their way, but not there yet.
To no one's surprise, former Colts and current Denver quarterback Peyton Manning is at the top of the list. Manning, the No. 1 overall pick in 1998, led the Colts to two Super Bowl appearances, been been named league MVP a record five times and his place in the Hall of Fame is assured once he retires.
The other not surprising pick -- outside of Tom Brady, Aaron Rodgers and Drew Brees of course -- is Andrew Luck. Luck has lived up to the talk of being the best quarterback taken No. 1 overall since Manning. Luck has led the Colts to the playoffs in each of his first two seasons despite offensive line problems, lack of a running game in his second season and not having his head coach most of his rookie season. He has yet to lose back-to-back games in his NFL career.
Remember Robert Griffin III, the player some thought the Colts should take over Luck in 2012? He's in the lowest tier. Griffin's knee injury has kept him from being in a higher category. He'll join Luck, Brady, Manning and others in the top category before it's all said and done.
