DAT's jersey number became of interest because of the NFL's rules on jersey numbers. Running backs are supposed to be numbered 20-49 while receivers can be 10-19 and 80-89. DAT's jersey number of 1 would have classified him as a quarterback, kicker or punter, which he obviously is not.
No. 13 would mean the Chiefs are classifying him as a receiver ... which doesn't really matter. Except for jersey purposes. The Chiefs can still use him however they want.
If you remember, Dexter McCluster was No. 22, a running back number, despite later becoming more of a receiver for the Chiefs.
