Give Mueller and Cam time to retool/rebuild the team. We could be good this year or it could take 2-3 years to get the right players and all of them on the same page.
Cam does bring accountability and dependability to the picture. Players like Chambers will have to perform or move on. Either you perform or you leave (sounds a lot like Shula). However, we have one major difference in the team now and the team when Shula took over. We had the QB already (Bob Greise), we're in a flux at that position. If DC comes back and can play in Cam's system great, if not we might have Green to play two years until Beck is ready. Lemon is a possibility, however, no one really knows what he can do yet.
Also the receiving corp needs to improve and become dependable.
If we can get stable at QB and depend on our receivers we should finally have an offense that compliments the defense.
I think the OL fix is on the way with this draft. Carey moving to LT in a new scheme should anchor the line. The Samoans should help in the middle for the next 5-10 years.
