Off-season reconstruction has four teams in motion: two up, two down
GM Doug Whaley buttressed new QB Tyrod Taylor by acquiring Charles Clay and Percy Harvin, the team's top receivers, as well as RB LeSean McCoy and guard Richie Incognito. Buffalo has its highest-scoring offense in 11 years.
Rookie coach Dan Quinn restocked his line by signing guard Chris Chester and center Mike Person and trading for guard Andy Levitre. Atlanta is No. 4 in rushing yards and the front five is ranked first by Pro Football Focus.
New GM Chip Kelly jettisoned his three best offensive players, then added QB Sam Bradford, RB DeMarco Murray and rookie WR Nelson Agholor. The '15 Eagles are averaging 58 fewer total yards than in '14.
Miami blew much of its budget on DT Ndamukong Suh (zero sacks), then signed receivers Kenny Stills, Greg Jennings and rookie DeVante Parker. Now Miami has the No. 23 passing offense and the No. 25 rushing defense.
