They are better pro prospects period than the 2006 group. Bookmark this post.
While Manase did play 11 games as a fullback in the NFL, Fui didn't play any games. Both were fullbacks either way. The 2020 running backs are better than the 2006 group (minus the fullbacks). I understand why you're arguing Brown as an all-time great is better, but people are still underestimating Allgeier. I believe that Allgeier will end up being better than Brown in retrospect (barring injuries), although I don't know if he'll get enough carries/targets to surpass Brown's career yardage. We'll see.
