Well, sort of.
The preseason (or NFL Lite) is a strange time for fans. Yes, it's technically NFL football, but it's not the real product. Starters see some time, but they only play about four quarters total over the first three games of the preseason, and most see almost no playing time in the fourth game, if they see any at all.
But these games are still important. The starters spend their limited time on the field working out the kinks and developing a rhythm with one another in preparation for Week 1 of the regular season.
