Scientist cooks up Pats formula

K.C. Joyner (a.k.a. The Football Scientist) is a regular contributor to ESPN.com and his most recent submission is on the four teams that should be most interested in Steelers restricted free agent receiver Mike Wallace.

Joyner comes up with a formula that weighs the need for a vertical receiver, level of first-round draft choice, and Steelers incentive level.

In crunching the numbers, he puts the Patriots atop the list with 25 points.

"That Tom Brady was able to post an 11.6 vertical yards per attempt (VYPA) mark (fifth best in the league) despite throwing 91 vertical passes to tight ends, speaks volumes for the genius of New England's creative play calling," Joyner writes. "However, it still doesn't mask the fact Brady's 10.9 stretch vertical YPA (SVYPA) ranked tied for 20th. (Note: Vertical passes are aerials thrown 11 or more yards downfield, while stretch vertical passes are thrown 20 or more yards).

"This problem calls for the addition of a wideout who can take over the Randy Moss role that helped Brady have one of the best seasons in NFL history in 2007."
