Feinga played in 3 NFL games, but I suspect that we'll see at least 3 of the current group make a roster.
Allgeier will end up with a better career than Brown and Katoa/Brown in 2020 will end up better statistically than the 3 in 2006.
It's true that Fui/Manase were better power runners than what we have now, but I might take the combination OL and RB group in 2020 over what we had in 2006. The 2 primary backs are averaging 7.5 yards per carry this season.
