It's hard to tell what's most impressive about Jimmy Butler's stretch of success during the Chicago Bulls' impressive playoff run.

Perhaps it's the fact that the second-year swingman, who only started 20 games during the regular season, has effectively contained Joe Johnson, Deron Williams and LeBron James. Or maybe it's that, while guarding James in Game 1 of the Eastern Conference semifinals, Butler managed to post 21 points and a game-high 14 rebounds.

Or maybe, and this is most likely, it's that Butler has played every second of Chicago's past three playoff games. The 23-year-old Butler was just the fourth player in league history to pull off that feat. According to the NBA, only Moses Malone (1981), Nick Van Exel (1995) and Allen Iverson (2005) had done that before. Not bad company.

Butler's "complete game" run will likely end soon. But if the Bulls want to maintain any hope of knocking off the heavily favored Heat, they'll need Butler's excellent defense on James to continue.

"[Butler's] a tough kid," Tom Thibodeau, the always-understated Bulls coach, said about Butler's impressive streak. "He's mentally tough, and that's what we need him to do right now."

If you're looking to take an extended trip on your motorcycle but don't have enough room to store all your luggage, you may want to look into a bagger.

The "bagger" is a motorcycle with built-in saddlebags on the back. A simple yet brilliant idea.

Baggers have exploded onto the bike scene over the past few years, with Honda, Suzuki and other manufacturers adding the bikes to their lines. The motorcycles have become so legit that they even have a magazine devoted to to them, Baggers.

"A bagger you could actually take across country and put your stuff in the saddlebags," Jordan Mastagni, editor-in-chief for Baggers, told KABC in Los Angeles, "you don't have to worry about jimmying up piece of luggage to the seat or a sissy bar or whatever."

From a style perspective, the addition of the saddlebags allows designers to play around with the bike's look. Last year dozens of cool and creative baggers were put on display at the annual Sturgis Motorcycle Rally.

In 2007, Scott Rigsby made history when he became the first double amputee to complete what is considered the most difficult endurance event: The Ironman Triathlon in Kona, Hawaii.

This year, he was part of a darker point of history: He ran the Boston Marathon when at least 13 people lost limbs as a result of the bombings.

But if anyone is uniquely qualified to help those amputees, it's Rigsby.

"I'm like the bookmobile," Rigsby said, likening his knowledge to a book service from his childhood in rural Georgia. "It wasn't easy back then to find new books to read, but we had this great resource available to us called the bookmobile that would literally drive to our home with books to check out. That is the service what I want people to know is available to them. Just let me know."

He says he knows it may take time for victims to be ready to start competing in races again. After all, it took him 19 years.

In 1987, Rigsby was thrown out of the back of a pickup truck on a southern Georgia highway, and then dragged more 300 feet while pinned underneath a trailer. Total time: Nine seconds.

What followed was 26 surgeries in 12-year span. Both of his legs were amputated. "I was ready to give up," Rigsby said.

A prayer from his mother on Christmas Eve in 2005 for "God to open up a door for him to run through" changed his mind, he said. As a double amputee, Rigsby would be the first to admit that the word run was far from his normal vocabulary, let alone an actual physical activity. But two months later he found himself engrossed in an article about Sarah Reinertsen, the first female leg amputee to complete the Kona Ironman and become a world champion for her classification.

Suddenly there was purpose back in his life.

He wanted to do the Ironman: 2.4 miles of ocean swim, 112 miles of bicycling and the 26.2 miles of a marathon.

The Boston Marathon was just one of many that Rigsby had competed in since his Ironman debut. He was not having his best race this year. When the first explosion went off, Rigsby was battling dehydration, kidney issues and some discomfort with the brand new legs. He was one of the first runners held short at the 25.7 mark on Commonwealth Avenue and confused when told the race would not finish.

As his condition worsened, an alert officer was able to make contact with medical to transport him to Tufts Medical for treatment. When Rigsby realized what was happening around him as the bombing victims came through, he knew he needed to help.

A study released by the Worcester Polytechnic Institute (WPI) should give Geno Smith, Manti Te'o and Tyrann Matthieu some hope for their NFL future.

Research conducted by several WPI students found that there's more value in second-round draft picks than in first-rounders. Players selected in the second round, the study finds, had 70 percent of the production of first-round picks at 40 percent of the salary.

Craig Wills, who heads the WPI's Institute of Computer Science, thought of the idea of rating draft picks after the 2012 draft.

“I was driving home thinking about all the pundits that come forward with their grades," Wills told the Worcester Telegram & Gazette. "'This team got an A, this team got a C,' and I'm thinking, ‘They don't know. The only way you can evaluate how well a team has done is to look at it historically, after the fact.' So that was the impetus for the idea of how can we look at how well teams have done and look at it relative to how much cost they’ve expended to acquire these players."

For their study, which examined players drafted between 2000 and 2012, researchers used two metrics to measure a player's success. The first was Approximate Value, a statistic developed by Doug Drinen, founder of profootballreference.com, which assigns value to a player's performance during a season. Under this measurement, Robert Griffin III, Alfred Morris and Russell Wilson were the highest rated players from last year's draft.

The other metric was "Appearance Value," a combination of games played, games started and "recognition" (Pro Bowl selections or other honors). Griffin III, Morris and Minnesota Vikings kicker Blair Walsh rated highly in this category.

The researchers found the Pittsburgh Steelers to be the most cost-effective team since 2000. They're followed by the Indianapolis Colts and the Green Bay Packers. The St. Louis Rams and the Cleveland Browns were at the bottom of the league.
