Sounds a lot like our 2009 team with Paulis at qb, Mike Williams at WR, Delone Carter at RB, and Chan Jones at DE along with a handful of others. We were in most games but ended up limping to a 4-8 finish.
Problem will be depth as after top 10 players and back end of the defense giving up chunk plays when Lewis doesn't get to the qb. Looking at your schedule I think you can get 6-8 wins and have enough on roster to make the bigger name P5 teams sweat a bit but year one of a rebuild always will have depth issues as many won't fit the new system.
Week 1 will be interesting vs our tempo especially if it's hot and muggy but year 3 is probably when you'll really make noise especially if Lewis stays in school. I'm sure AGG will make some plays but we've got cover corners that can hang with eilte wr's and a ball hawk safety if buckshot locks in. My question for you is how do you feel about your OT's because our DE group is elite and not sure AGG will have time to work downfield unless you can slow them down.
