For me, this choice was much easier than the poll for the best QB. JJTBC, hands down. Consistent production despite working with the least impressive offensive line. Similar thought process to my reason for putting Persa as best QB: did more with less. Only difference is that Jackson had Thorson as QB, which did take some of the pressure of him, but most defenses were geared up to stop Jackson.
If I recall correctly, advanced statistics also showed that he did more with less blocking, with a greater percentage of his rushing yards attributable to him than his offensive line. (Adjusted line yards, I think it is the statistic that was referenced, but I can't remember where the reference is that broke this down for JJTBC specifically...anyone remember?) Put him behind the 95-96 OL? Now that's a scary thought for opposing defenses... I don't think any other NU RB was hit in the backfield and still produced positive yards more than Justin Jackson.
Loved Darnell and would consider him second to JJTBC. I have particularly fond memories of this TD run in the Citrus Bowl, while he was recovering from the flu:
(one of my favorite announcer calls: "You think he's feeling okay?!? You think he's feeling okay?!?")
On a side note, I love watching highlights of the 95-96 teams - I had forgotten just how good they were in all three phases of the game. Although we have had success since then, I don't think any NU team has been as complete as those Barnett teams were. Too often in the ensuing years, we have had a good offense with a sub-par defense, or a great defense with a mediocre offense. Can't think of many other seasons where both sides of the ball, plus special teams, were good at the same time.
