There are usually more questions than answers this time of year. Here are five questions I'll be looking to answer Friday night as the Oakland Raiders open the 2015 preseason against the St. Louis Rams at O.co Coliseum.
1. How much will the starters play? It will interesting to see how long they stay in considering quarterback Derek Carr missed quite a bit of the offseason program, and with all the new pieces on the roster.
2. What will happen in the return game? Trindon Holliday gets first crack at both the punt return and kick return jobs, but several players could be vying for the job.
