Reasons for each move:
A. Dolphins-Rams: The Dolphins look poised to make a splash this year, and if they miss out on Peyton Manning they could go ‘all-in’ on getting a quarterback. From the Rams perspective, they get a ton of picks the next two years and still get a top 10 player.
B. Eagles-Redskins: The Eagles have a number of extra draft picks, and few primary needs. One of their biggest needs is at MLB, where the top player Luke Kuechly should be well off the board, by the time the Eagles pick. From the Redskins perspective, they are a team in need of both starting and depth players so a trade back that lands them multiple picks is a big win for them.
C. Bears-Bills: The Bears lack of receivers is a big issue and needs to be fully addressed this year. I think they will make a move up for one of the top 2 guys. The Bills can be pretty confident with this move back of still landing a top pass rusher, and they get some extra picks in the process.
D. Chargers-Seahawks: The Chargers are desperate for offensive line help this offseason and a LT has to be a top priority. Their offense is extremely talented, but they lack an offensive line which needs to be fixed. From the Seahawks perspective, there is a deep class of first round pass rushers, plus Ryan Tannehill on the board. Seattle can move back a couple spots, and still pick up one of their top needs.
E. Lions-Redskins: The Lions really want to land one of the top offensive linemen in this draft class, and their only way to do so will probably be to trade up. While they will miss that 2nd rounder, protecting Matthew Stafford has to be a priority this year.For the Skins they weigh the risk of losing out on Ryan Tannehill, with adding another pick for their rebuild.
F. Broncos-Browns: The Broncos move up a few spots to nab one of the best players in the draft, who also happens to fill a need for them. As for the Browns, with Tannehill and most of the receivers off the board, they pick up some extra selections and still can land another top 25 talent. (Note: I previously had this pick a 4th rounder in 2012 as compensation, but I changed it to a 2013 3rd rounder)
G. Packers-Pittsburgh: The Packers jump up to ensure they land the last of the premier pass rushers. With few major needs they can sacrifice some later round picks.For the Steelers they pick up a pair of picks for moving down in the draft. Pittsburgh is in desperate need of cheap, young talent, as their age is beginning to show and they are in serious cap trouble this year.
H.Tampa Bay-Pittsburgh: The Buccaneers need to land a receiver, and it just so happens that their new head coach had such a player last year at Rutgers (Sanu). The Bucs jump ahead of all the WR needy teams at the top of round 2, and land a guy who fits them perfectly. For the Steelers they continue to add extra picks.
