Training camp is in full swing and there are still plenty of questions to answer. With another week of training camp set to begin, we look at some of the riddles that have yet to be solved. Each week, I'll answer your questions, which you can tweet to me at @Mike_E_Kaye on Twitter.
@Trevor_Newcomb: How much do you think TJ Yeldon will contribute?
Answer: A short answer would be that he will contribute a lot or at least that's what I expect. He's a nice mix of his potential backups, Denard Robinson and Toby Gerhart, and is probably the most complete running back on the team.
