That's a great post Henry, but it really doesn't paint the real picture.
Putting all of the locker room Portis antics aside, your stats above leave out a few things. I don't have them handy, but there was a period of time where Portis literally had the worst hands as a receiver of any player in the league. I'll try and locate the article. I believe it was a two year period, in reference to dropped passes. His hands were awful.
Welp, for your benefit I googled 'portis dropped passes' just to see what I could find, and nothing useful came up. I then tried 'dropped passes nfl' and found this:

According to this site, Portis had two ... not great years in that category.
In 2005 he had a drop rate of 14.63%. That put him at 27th worst in the league. Behind that other not-elite RB Adrian Peterson.
In 2008 his drop rate was 11.11%. That put him at tied for 41st worst ... I think. I was starting to lose track.
In 04, 06, and 07 his drop rate was pretty boring. Somewhere between 5% and 8.7%.
See this is the thing. People remember something. Probably a bad drop. Or a few bad drops in a row or something, and then project it upon his entire career. That's exactly how it was with the fumbles. He had one not great season regarding fumbles (this I don't have to look up. I remember it from talking about this many times before). One season he fumbled the ball 6 times ... and suddenly people think he's a fumbler. He wasn't. He had one bad season in that category.
So when people argue that he was not elite, what they are really arguing is that he wasn't PERFECT. Well, I concede that. He did drop the ball sometimes. And he did fumble sometimes.
But you know what? So did everyone else.
He was a very good blocker, but he unfortunately laid out so hard on many of those blocks, that he could not then go out for a release pass. That was not the case with Betts.
Unless you were the coach and told him to stop committing to his blocks and go out for a pass, I'm not sure you have a point here.
Elite players show up in playoff games.....when it really counts. That was the biggest differentiating factor between Portis and Riggins.
Now that's a fair point. Portis was not Riggins. I've argued THAT many times in the past as well. Then again, nobody, and I mean nobody, can match Riggins in the playoffs. Not Emmitt Smith. Not Sweetness. Nobody.
Speaking of Sweetness ... did you know that in nine playoff games he only had one 100 yard rushing game, averaged 3.51 yards a carry and only scored 2 TDs?
OJ Simpson ... One playoff game. 15 rushes for 49 yards. No TDs.
Huh.
