I think you being a little disingenuous in your assessment of the supporting cast........
Seattle has an elite defense...#1 in the NFL and a top 5 running game....above average is an understatement.
Miami's defense was badly flawed with a bottom quarter of the league run defense and running game.
With those supporting cast differences....it's unfair and innaccurate to claim Wilson is greater than Tannehill at this point....just as it would be to claim he is greater than Marino...who never had an elite defense or running game.
By your reckoning....Trent Dilfer, Jim McMahon & Brad Johnson to name a few are greater than Marino, Tarkenton, Kelly & Fouts....I don't think so.
I don't believe Wilson could have led Miami farther than Tannehill last season with the flawson this team.
