ProFootballFocus has a recap of 2015 recruiting classes and has a chinsightful table on the number of snaps for each true freshman. The link is below:

Dude must have even worse of a life than me. Second, I'm surprised at how many snaps Miller played with almost never hearing his name all year. I know he was on special teams as a starter and barely played CB, but for 121 snaps, he only had 5 tackles and 1 INT. BBK was productive in his 141 snaps with 34 tackles and a sack.
Also, it's worth going down to USC and seeing how many redshirts Sark burned this year.
