I was looking at the Chargers roster via chargers.com/team/roster and it seems they have given out the rookies their numbers.
It doesn't mean much but its fun to know what number the new guys are going to wear.
Ryan Mathews- one of the few people who doesn't have a number according to the site but he has said he will probably wear number 33
Donald Butler- Dobbins old number, 51
Darrell Stuckey- 36
Cam Thomas- taking Jamals old number, 76, no pressure there
Jonathan Crompton- new clipboard holder will wear number 8
Dedrick Epps- 87
