Is Phil Mickleson the Mark McGwire of the PGA Tour?

If you have followed the PGA Tour any at all this year, you know that square grooves (especially as it pertains to wedges) are against the rules. The theory being that players will not and should not be able to get incredible spin on wedge shots. So, with all of that being said there just happens to be a little rule that says if you use Ping wedges made before 1990, your wedges can have square grooves on them. I know that is absoultey craxy but it has something to do with an agreement between Ping and the PGA Tour that I do not completely understand. From what I do understand, most players are abiding by the new rules and not using square grooves. There are a few players, such as Phil Mickleson, who are using the square grooves (remember that the square grooves have to be on a Ping club made pre-1990). So at the Farmers Insurance Open this past week, Scott McCarron (PGA Tour player) made these comments regarding Phil's use of square grooves, "It's cheating and I'm appalled Phil has put them in play."

McCarron was way of base, and I understand he has apologized regarding these statements, simply because if the rules say you can do something you can do it. If MLB says you can use steroids, along with the federal government, you can do it. If the NBA says you can take 4 steps instead of 2, you can do it. If the NFL says it is legal to take of your cleats and throw them up in the air to knock down a field goal, you can do it. If MLS says you can pick the ball up and carry it you can do it. If the PGA says you can use square grooves only if you use them on pre-1990 Ping clubs, you can do it. Rules are rules. Now, Mickleson acting like a little baby in the wake of McCarron's comments is a whole nother (is nother a word) issue.
