Scott's birthday
Today is Scott's 36th birthday. Wow! It just seems like yesterday that I was meeting the cute returned missionary who was visiting Tucker 21. It's amazing to think that he is now all grown up with a real job and 3 kids. Scott is a great husand, a great father and pretty sexy too. He rides his bike about once a week to stay in shape. So if you see him today, be sure to tell him Happy Birthday.

Happy Birthday stat master... I am getting robbed on our football picks!
Happy Birthday Scott!
Scott,
This is my birthday present to you.

Passer rating
From Wikipedia, the free encyclopedia
(Redirected from Quarterback rating)

Passer rating (known as passing efficiency or pass efficiency in NCAA football) is a measure of the performance of quarterbacks or any other passers in American football (gridiron) and Canadian football. There are at least two formulae currently in use: one officially used by the National Football League and the Canadian Football League, and one used in college football. Passer rating is calculated using each quarterback's completion percentage, passing yardage, touchdowns and interceptions.

[edit] CFL and NFL
The NFL's current passer rating (also known as quarterback rating) system was conceived by Pro Football Hall of Fame's retired vice president Don Smith in 1973. The system is a sliding scale design, where outstanding performances meet diminishing returns faster than sub-par ones. The best passer rating that a quarterback can obtain is 158.3, while the worst is zero. The architects of the passer rating had 66²⁄3 in mind as the "average" score, but as styles of play have changed, so have average passer ratings. The cumulative league-wide average passer rating for the years 2000 through 2003, all inclusive, was 78.9 (the figure is typically rounded to the nearest 1/10 of a point); however in 2004 the league average was 82.8. In 2007, the average was 83.5. Passer rating has been applied to all seasons.
[edit] Calculation
Passer rating is determined by four statistical components, each of which is computed as a number between zero and 2.375. The benchmarks for these statistics are based on historical averages. If any of the raw components are beyond the limits of zero or 2.375, the component is set to limiting value of zero or 2.375 as the case may be.
The component for completion percentage, C, is calculated as:
The component for yards per attempt, Y, is calculated as:
The component for touchdowns per attempt, T, is calculated as:
The component for interceptions per attempt, I, is calculated as:
The four components are then added, divided by 6, and multiplied by 100. Thus, the formula for passer rating can be given as:
.
The Canadian Football League uses the same formula as the NFL. [1]
[edit] Perfect and Zero NFL passer ratings
Since each component of passer rating can be at most 2.375, the maximum passer rating is
.
A perfect passer rating therefore comprises all of the following:
a completion percentage of at least 77.5%:
at least 12.5 yards per attempt:
at least 0.11875 touchdowns per attempt, or at most 8.42 attempts per touchdown: and
zero interceptions:
A zero passer rating comprises all of the following:
a completion percentage of at most 30%:
3 yards per attempt or less:
zero touchdowns:
at least 9.5 percent interceptions:
A passer who does not throw an interception has a minimum rating of 39.6.
[edit] NCAA
Passer rating, known formally in college football as passing efficiency or pass efficiency, is based on player performances. The NCAA passing efficiency formula is:
The component for completion percentage, C, is calculated as:
The component for yards per attempt, Y, is calculated as:
The component for touchdowns per attempt, T, is calculated as:
The component for interceptions per attempt, I, is calculated as:
The four components are then added. Thus, the formula for passer rating can be given as: (C + Y + T + I)
The NCAA passer rating has an upper limit of 1,261.6 and a lower limit of -731.6. The upper limit value results if every pass thrown is a 99-yard touchdown and the lower limit if every pass is thrown for a 99-yard loss. A passer who throws only interceptions will have a -200 rating. [2]
[edit] Records
[edit] CFL
In CFL football Dave Dickenson of the Calgary Stampeders and British Columbia Lions has produced some of the highest professional passing efficiency numbers. Although limited by injuries in 2005, he set two regular season records with a 74 percent completion percentage and an efficiency rating of 118.8. His numbers for the year were: 253/342, 3338 yards, 74% completion rate, 21 TDs, 5 INTs. He opened the 2006 season by setting a CFL single-game passing efficiency rating record of 150.61. He capped 3 of the 4 criteria for passing efficiency and was 28/34, 362 yards, 5 TDs, 0 INTs.
[edit] NFL
Steve Young currently holds the NFL record for the highest career passer rating for any player with at least 1500 attempts with a mark of 96.8. The highest passer rating for a complete season is 121.1 set by Peyton Manning in 2004. Also in 2005, rookie Ben Roethlisberger posted a mark of 98.1, setting a new record for first-year passers. There have been 34 quarterbacks to complete a game with a perfect passer rating of 158.3 (and only 4 to have accomplished this more than once), the most recent being Ben Roethlisberger in 2007.
[edit] NCAA
In NCAA Football Bowl Subdivision (formerly division I-A), the career record for passing efficiency is held by Ryan Dinwiddie of Boise State, who had a career mark of 168.9 between 2000 and 2003. The single-season record belongs to Colt Brennan of Hawaii, who amassed a passer rating of 186.0 over the 2006 season, while the freshman record belongs to Michael Vick of Virginia Tech, whose rating during the 1999 season was 180.4.

Happy Birthday, Scott! This is the real erika w. commenting, not that foolish pretender. Sorry I couldn't get to the bundt cake store for you but I've been a little under the weather. Still, I'm sending you sugary frosting birthday wishes via the web.
Thanks Jason for that great diatribe on passer ratings. It was very enlightening, although very suspenseful as the actual formula I was looking forward to committing to memory was curiously absent. I guess you must have pasted this in from the website rather than typing it in from memory as I would have hoped. You can't copy in mathematical formulas into blogs and have to use special characters to type them in.
