Yeah there's a bit of reaching with the Tanny comparison as if it is apples to apples. One has Derrick Henry behind who has 1200+ yards already, 5.0 average per carry and in this whole last month we're going on about here has ran for:
188 yards 8.17 ypc 2tds
159 yards 8.37 ypc 2tds
149 yards 5.73 ypc 1td
103 yards 5.72 ypc 2tds
Let me know when Watson has a guy behind him that can be that type of threat and push the RPO success to such a high threat because teams want to stack the box against him. While Hyde has been surprisingly efficient and Duke (when they bother to utilize him right) neither are the threat Henry is when he touches the ball. That's just a fact of the matter.
With that said, Watson does have some inconsistencies in his game and falls back on tendencies he shouldn't. He will press for the big play too often and sometimes hold the ball as we know. He will bypass the shorter open man seeking his downfield option too. He is also a quarterback in his third year in the league, regarded as one of the top quarterbacks in many circles and has room to grow. Acting as if he has reached his ceiling at this point is asinine. I mean we're over here throwing out Tanny to measure against and how many years was he inconsistent? So even with Watson having some inconsistencies he's still measured as one of the top quarterbacks in the league. I would think after years of Schaub, Banks, Yates, Mallet, Fitzpatrick, Carr, Hoyer, Keenum and Osweiler we could appreciate having a quarterback who is young, still developing yet still a top ten quarterback in the league.
But apparently even little inconsistencies in only his third year are enough to close the door on the chapter. How that makes logical sense I have no clue. I would think he's a five or six year vet with this talk going on the way it is. And acting as if coaching isn't a part of it is also a reach. Put Watson with Andy Reid and you would see even more production. Our offense lacks identity. One week we look one way, the next something totally different. If the offense/playcalling isn't consistent how do you expect players to be so? Not to mention we have no defense. If your defense is constantly stacking the box against you then your offense (i.e. Watson) will feel pressed to do more than he should. It's what playmakers do. Now picture him with a defense that can get him the ball in better field position. One that can hold opponents out of the endzone (especially in the redzone) and that can create turnovers? Do we have that? Not even remotely close...
So no. It's not Watson's current inconsistencies that will hold us back from a title. It takes a team to win. Period. Otherwise Aaron Rodgers would have more than one trophy (a year his defense was top five by the way) and Brees as well (when his defense was a turnover gathering machine). We lack the components in other places and, yes, one side of the ball effects the other. It effects playcalling and the mental state/approach.
