I don't really think the Dolphins are 'offseason champions' as much as people make out. Aside from Wallace who definitely we overpaid for (but then again, everyone big more or less is overpaid in Free Agency), we replaced Dansby and Burnett with Ellerbe and Wheeler - 2 younger more or less as good (on paper) players that actually cost 2 million less in cap space. We signed Brandon Gibson and Dustin Keller (1 year deal to replace Fasano who went for more money to Kansas City). Big woop.
We let a guy who when drafted was the highest paid O-Lineman ever go too. And rightly so too, he's not the player we drafted anymore. Still a good lineman when healthy, but I'm glad we didn't keep him - I didn't want him. We've signed injury prone linemen to big deals in the past and it's blown up in our face - Jake Grove and Justin Smiley spring to mind. Long said he was in the best shape he'd been in ages recently - but he said it before last season too, and he ended the season again on injured reserve. Was worried by our last ditch attempts to resign him because he's on the decline. That said though I like Jake and hope it works out nonetheless, his first 3 seasons were great for us after all.
Think Wallace is a good move in that he takes the top off a defense, and Tannehill was decent going deep. Should help Hartline, Bess, Keller and Gibson get free too. Not to mention opening up the box for the running game if Lamar Miller is as good as people seem to think.
