I just ran some numbers for 2008 (a year where portis did well). taking all rushers with at least 190 carries (26 in total) this is how portis stacks up...
he's +1.65 standard deviations above average in carries making him 86% better than the average back
he's +1.43 st dev above the mean in attemps per game making him low 80% better than the average back
he's +1.4 st dev above the mean in total yards gained again making him low 80% better than the average back
he's +.16 st dev above the mean in yard per carry (at 4.3 ypc) making him 10% better than the average back
he's +1.22 st dev above the mean in yards per game making him 80% better than the average back
he's +.02 st dev above the mean in tds scored making him 1.36% better than the average back
he's -1.27 st dev below the mean in longest run making him 80ish% worse than the average back
he's +1.61 st dev above the mean in first downs making him 85% better than the average back
he's +.39 st dev above the mean in first down percentage making him 26% better than the average back
he's +1.3 st dev above the mean in gains of 20+ yards making him 76% better than the average back
he's -1.09 st dev below the mean in 40+ gains making him 70% worse than the average back
he's +.22 st dev above the mean in fumbles lost making him 11% worse than the average back
what does this mean? I'm not sure much (especially because he had the 3rd most attempts in the league) but as its just one year (a year when portis was pretty good, a year where it was also heavily front loaded, a year where his line fell apart, etc) but I think it says that portis is good. Yes, he doesn't explode for huge gains, but he does better than we give him credit for with 20+ runs (certainly better than I give him credit for). That said, the fact that he's just 10% better than average in yards per attempt (in a year where he matched the best average that he's had in DC) is painful.
