ORLANDO, Fla.--Josh Miller wasn’t looking to start a business, it was an accident. The former National Football League punter, who starred with the Pittsburgh Steelers and the New England Patriots, ended up as the inventor of a putting aid because of his son.

“My seven-year-old couldn’t putt to save his life,” said Miller, who exhibited his product, The Wheel Deal, at the 2011 PGA Merchandise Show. “He could do everything else. I was helping him with his Legos, was working on one of the tires and instantly, it was like, Hey, I think I’m on to something. Sadly, I broke his car but I got him a new one. I went to Home Depot and came up with something that taught him how to keep the tire and the putter on the ground, because he wanted to keep lifting the club up.”

Miller’s idea is a strange-looking attachment. It’s a wheel at the end of a crooked arm that hooks onto the putter shaft. The idea is to drag the putter away from the ball on the backstroke, causing the wheel (a rubber tire) to roll. The angle of the wheel is adjustable for the putter’s lie, and works for players who use a square-to-square stroke or an open-and-closed (swinging gate) stroke. I picked it up and immediately discovered that I, like Miller’s son, tend to pick the putter up instead of sliding of back.

Wednesday was the 9th annual Demo Day at the PGA Merchandise Show in Orlando, and Golf.com senior producer Ryan Reiterman was there to check out the latest products for 2011. Here are some of the highlights. For more exclusive looks, follow SI Golf Group on Twitter.
