Playing time in a preseason opener is a difficult thing to read -- starters are generally gone after a quarter, so if you're barely playing as a result of that, it's a good thing; if you're barely playing as a backup, it's probably not a good thing.
The "playtime percentage" participation charts for the Bucs' preseason opener at Cincinnati are out, and there's some interesting things to be gleaned from it all. The Bucs' starting offense played 21 snaps -- two drives -- and the starting defense played 13, with the starting corners playing longer due to injury-related depth issues.
