We're halfway through the NFL preseason. While much of what we've seen still isn't NFL reality, we're finally starting to get a good idea of what teams might look like once the regular season arrives.

This is when players first start getting excited about being on the football field. They've made it through the meat-and-potatoes of training camp and are finally getting back to a regular football schedule. Some of the veterans are even looking ahead to roster cuts. I know I would get sick of having 90 guys crowding my locker room.

Coaching staffs are closer to getting their teams in regular-season form, too. Heading into Week 3, most have 50 of their 53 roster spots mentally filled out. We're beginning to get a clear idea of which guys the coaches value.

All of this means that while we're not seeing finished products, we are starting to see the formation of teams. This is why this week's power rankings are going to look a bit different than after Week 1 of the preseason, when many actual starters and lineups weren't even on the field.
