I have higher expectations for the team this year than I have had in quite some time. Not saying that I expect them to win the division, but I think they can actually compete for it legitimately this year. Although they are lacking in enough areas to prevent me from saying they are ready to be "really good", I do think they are moving in the right direction.
Miami is an extremely young team. I expect some painful losses this year and mistakes still to take place. That's gonna happen anyone who thinks otherwise is fooling themselves. This isn't a 12 or 13 win team by any stretch. Win 8 or 9 games, be competitive against the "good/great teams" (ie...Atlanta, N.O., N.E., Cincy ...etc,), fight for a wild card spot and I will be happy. Tannehill isn't going to become Eli/Flacco overnight (which I think his ceiling is like those 2 and not a Rodgers/Brees type). Quarterbacks need a good 4 years or so before it clicks for them (ie Eli and Flacco). So I expect the growing pains to continue to an extent. The offense is better, but far from where it needs to be though.
This is a process and while Miami is moving in the right direction they aren't ready for the big time just yet
