As a player, your number carriers a special meaning....it's what some casual fans know you by and it gets put on everything from your helmet to your sticks. When you get traded or sign with a new team, there's a chance that your number is not available.....you have two options: Call Larry Flowers and pick up the newest Rolex and trade your teammate for that number or pick a new number and start a new era. An important decision, you typically only get one chance at.
