The running back is wearing No. 28 this season rather than his trademark No. 2.
“I just felt like No. 2 was more of an all-purpose back's number,” he said. “I wanted to wear a tailback's number this year.”
Speaking of Rainey's number, it is No. 1 this season. He asked to switch from No. 3 to take the departed Janoris Jenkins' old jersey.
Hope it helps out..
