As I recall...when we went on our winning streak our defense was still bad. The one thing that wasn't bad was our offensive line and running game...which in turn transformed Tannehill from a middle of the pack starter to a possible franchise QB (considering the circumstances - running game and good/great o line play). On paper, our defense is already better than it was last season...yet the strength of the team could possibly become a weakness, especially if Pouncey is injured this year (what are the chances?).
If you are going to be smart (cheap by another definition), you will get what you pay for. I wish we had paid for Leary...I also wish we had picked up Jonathan Cooper when he was to be had for a song...I want to be a billionaire, so it's not to late to accept my fate and wait on better dyas.
