Most overvalued fantasy QBs

The glut of quality fantasy quarterback prospects has led to a number of players being undervalued at that position -- click the links above for my undervalued players at four positions. Oddly enough though, it hasn't stopped fantasy owners from overvaluing a number of passers.

This first of a four-part series looks to assist fantasy owners by identifying players who are overvalued, starting with the 10 quarterbacks who fall into this category. These players are being taken earlier in drafts (as determined by ESPN.com's average draft position) than they should be based on my own value analysis. They range from long-tenured veterans (whose name value carries too much weight with some fantasy owners) to rising young players of whom some fantasy owners are expecting too much.

Here are my 10 most overvalued fantasy quarterbacks.

1. Tom Brady

Current ESPN Live Draft ADP: 21.5
Current ESPN Live Draft positional rank: No. 4
The Football Scientist (TFS) positional rank: No. 8

Why is Brady being drafted so early? He ended the 2012 season in a slump. His 10.1 vertical YPA (VYPA, a measure of productivity on passes thrown 11 or more yards downfield) ranked 28th in the league last year and his stretch vertical YPA (SVYPA, production on passes thrown 20 or more yards) placed 23rd.
