I have to agree with this sentiment.
I was worried they/he rushed back from injury too soon. I hope it's not career ending. Even though he was a division rival, I've always liked how he carried himself on and off the field. I wish him the best.
But he didn't, despite the narrative.
Grigson drafted 4 receivers in 4 years: Hilton (3rd), Brazill (6th), Moncrief (3rd), Dorsett (1st).
In the same time period, he drafted 6 OL: Anderson (7th), Thornton (3rd), Holmes (4th), Mewhort (2nd), John (7th), Good (7th).
Then this year, he drafted 4 more OL, including Kelly in the 1st. In five years, that's 4 receivers, 10 OL. Even "early" picks -- which to me is first and second rounders -- is 2 OL, 1 WR. Add in the third round, and it's still 3 OL and 3 WRs.
Grigson largely failed to fix the OL for four years, no question. But it's not because he didn't try, and it's definitely not because he spent too many picks on receivers.
In theory, yes, the Colts at their best could probably beat any team in the league. The offense would have to avoid mistakes, the defense would have to tackle well, and they'd probably still need some help from the other team in the form of missed opportunities (Rivers missed 3-4 TD throws on Sunday). They could get hot, stay healthy, and knock some teams off. It would be awesome if they were humming in December and January and made it to the Super Bowl, but don't hold your breath.
In practice, this year's Colts are a second tier team, at best. The OL is a work in progress (positive things are on the way, I believe, but the protection is still leaky and the run blocking is even further off), the QB and receivers aren't consistently on the same page. The defense can't cover the middle and can't consistently rush the passer. The coaching staff hasn't proven that they have the ability scheme and strategically minimize these weaknesses AND maximize the obvious strengths. In fact, in the biggest test of this ability -- late in the Denver game -- the coaching staff blew it.
If the Colts were able to play to their full potential every single week, and stay healthy, and if the coaching staff pushed the right buttons every game and in every situation, you might have a 13-3 team with a first round bye. But even then, you're probably looking at the 2010/2012 Falcons; that team even won a playoff game, but wasn't a great team, and quickly regressed (4-12 in 2013, a year after going to the NFCCG). This team appears more likely to play below expectations than to exceed expectations, sadly. Just not enough playmakers, especially on defense.
The hope is that the last two draft classes keep going in the right direction, and you get another two draft classes that pan out. Doesn't mean the Colts aren't trying to contend in the meantime, but it's going to be a couple years before the Colts will be considered one of the top teams in the league. And that's assuming things go well and the staff does the right things over the next two offseasons, which isn't a given.
