Sign center Alex Mack. He would allow Wiz to move to left guard and Barnes to the right side, strengthening the line.
Sign a defensive end: either Greg Hardy or Jared Allen. This would allow Houston to move back to the other side and relieve him of being the main focus of opposing offensive lines.
Sign linebacker Brian Orakpo. This is low priority, but it would improve the defense tremendously.
Sign a cornerback: either Aquib Talib, Alterraun Verner, or Brent Grimes. One of them along with Porter and Hayden would create an above decent cornerback group.
Trade down draft picks to select a defensive lineman with their first round pick and gain another second round pick. Maybe Rashede Hageman, Kony Dealy, or Dee Ford.
Select a tall wide receiver and an offensive lineman with their second round picks. WR maybe Kelvin Benjamin or Jordan Mathews. OL maybe Cyril Richardson or Antonio Richardson.
Trade down their third round pick to get an additional fourth round draft pick. With their third pick select a quarterback. Maybe Jimmy Garropollo, Zach Mettenberger, or AJ McCarron.
With their two fourth rounders select a cornerback and defensive lineman. CB maybe Jaylen Watkins or Chris Davis. DL maybe Justin Ellis or Josh Mauro.
With their sixth round pick select either a linebacker or running back. LB maybe Denicos Allen or Howard Jones. RB maybe Tyler Gaffney. If Deanthony Thomas is there then he is a must draft because he can be used for the return game as well as an offensive weapon.
With their seventh round pick select an offensive lineman. Maybe Cornelius Lucas or Ryan Groy.
This would be an achievable an ideal offseason. This would be the first step towards making the playoffs next season.
Hopefully Peyton Manning retires as well.
