Reebok reported receiving over 15,000 orders for Bush's Saints jersey, even though his jersey number with the Saints had not yet been determined. Bush had petitioned the NFL to wear the number 5, which he has worn throughout his high school and college careers. However, in order for him to wear that number, the NFL would have to revise its numbering regulations, which require running backs to wear a number between 20 and 49. Bush was allowed to wear the number 5 during the Saints' minicamp practices pending the NFL's ruling. On May 23, 2006, the NFL competition committee officially rejected his request, and on May 25 it was officially announced that Bush would be wearing number 25, acquired from Saints running back Fred McAfee. Although Bush had earlier pledged to donate a quarter of the money he received from jersey sales to Hurricane Katrina victims if allowed to wear the number 5, he later said he would make that donation no matter what number he wears. As part of the deal with McAfee to wear the number 25, Bush agreed to allocate half the money to charities of McAfee's choosing, the other half going to charities of Bush's choosing. McAfee pledged to donate his share to Katrina victims in his home state of Mississippi. Bush was second to Peyton Manning in NFL endorsement deals, amounting to roughly US$5 million annually. He signed contracts with Pepsi, General Motors, Adidas, Pizza Hut and the Subway restaurant chain. Amazed by the warm reception he received from the fans in New Orleans as well as the magnitude of the devastation caused there by Hurricane Katrina, Bush expressed excitement about playing with the Saints and pledged to help the city recover from the hurricane. On May 15, 2006, Bush donated US$50,000 to help keep Holy Rosary High School, a Catholic school for students with learning disabilities, from closing. During training camp, Saints receiver Joe Horn dubbed him "Baby Matrix" because of his seemingly impossible evasive maneuvers (apparently comparing him to the movie The Matrix, which features characters who move faster than humanly possible to dodge bullets). Bush's rookie season had both ups and downs, although as the season wore on he became more productive and integral to the Saints' surprising success. In the first game of Bush's NFL career, he amassed 141 total yards against the Cleveland Browns. He carried the ball fewer times
