I'm not going to bother supporting the following statement with stats, hopefully common sense will be enough. In the NFL the better team wins an overwhelming amount of the time. Thus it's not surprising that the better teams end up in the playoffs each year. Carolina is better than Miami by a wide margin at this point in time.
Cam > Tannehill (Tannehill is a ..good.. developing young QB, but this isn't even close.)
Smith/Lafell/Ginn/Olsen > Wallace/Hartline/Matthews/Clay (Wallace would compete for best WR on the field but as a group I give our guys the edge)
Williams/Stewart/Tolbert/Cam > Miller/Thomas (Miami's running game is respectable but Cam puts us over the top here again)
Offensive line (Carolina grades out better in every meaningful category, Martin and Incognito both gone now as well)
Defense (Does this merit any discussion whatsoever? )
Special Teams (Field Goal % Carolina, Touchbacks Carolina, Punting Miami, Returns Push)
Summary, Carolina is better over the entire field. Biggest concerns Carolina will have on defense, don't let Wallace blow the top off our secondary, seriously doubt protection will hold up long enough for that to happen anyway. On offense....Cameron Wake. Overall, be disciplined on Special teams and don't allow Miami to change the game cheaply and protect the ball. Do these things and the better team will win...Carolina!
