I think the critically important factor in your statement here is, it all depends on WHO the " You " is you are referring to. Most "You's" judgements didn't really get us anywhere and I'm not very comfortable with half of FH as You's either.
IMO. realize to have success you need a quality and not necessarily the best QB, with, and the with just as important, a quality OL, WR, RB and TE, and thats basic football knowledge 101...For real success you can't have one without the other, oh ya and through a good defense in there too...
And then there is the Tannehill sydrome. Didn't do so well with the Dolphins so called rebuild. Funny thing he seems to be lighting it up with actual quality around him ( Hmmmm maybe that is important ? )
Its an interesting point kind of like what came first the chicken or the egg ?
Oh ya the medical evaluation also not a sure thing and in this serious of a injury just another crap shot the organization better be thinking about...
