How top NFL QBs’ performance is affected by age, then and now

This graphic, originally published on June 16, 2013, allows you to compare performance ratings for different quarterbacks at different ages.

To create the performance ratings, the Globe used a formula developed by David Berri, a sports economist and professor of economics at Southern Utah University. The formula (Total Yards) - 3*(Passing Attempts) - 30*(INTs) is based on statistics compiled for every season a quarterback played. Quarterbacks eligible for the statistical sample started at least 10 games in at least 8 seasons from 1960 to present. The equation aims to measure player performance by linking statistics to wins and to mitigate factors such as team strategy so QBs can be equitably compared.

Yale professor Ray Fair used the performance ratings to estimate the effects of aging on NFL quarterbacks. Fair emphasized that many other variables affect how an athlete performs in a given year aside from his age.

RISE: ARTIST ADAM O’DAY SEES BOSTON IN A DIFFERENT LIGHT

Age: 32

Hometown: Born in Tennessee, moved eight times, settled in Southie at the Distillery with wife Meghan.

Think of: A modern mix of expressionism and impressionism, sometimes with a street-art twist. “I just try to paint exactly how I want to and how I feel like I need to. That way, whatever I paint is going to be my hands.”

What caught our eye: A vibrant, vivid, imaginative take on the city of Boston.

Lightbulb moment: “Somewhere between getting out of college in 2005 and now, I just said ‘I’m just going to try to make a go of it as a professional artist.’…I guess it was about a year and a half ago that I made that decision.” Before making a go of being a professional artist, O’Day was an engineer and designer for the Navy. He graduated from the Art Institute of Boston at Lesley.

Naumkeag shows off its rooms inside and out in Stockbridge

STOCKBRIDGE — Naumkeag “cottage” has 44 rooms — that is, if you count only those in the house. Outside garden rooms, designed long before patios and backyard barbeques became a way of life, bring the house outdoors and the outdoors inside.

This summer residence overlooking the Housatonic River Valley was built for Joseph and Caroline Choate in 1885 in the shingle style with a Norman French influence evident in its two steeply pitched towers. Choate was a lawyer and later ambassador to Britain at the turn of the 20th century. Naumkeag is the Native-American name of Choate’s hometown, Salem.

The Choates’ daughter, Mabel, inherited the property and in 1958 bequeathed the house, its contents, and the land to the Trustees of Reservations.
