Imani Cross would have been a great back in Nebraska's vintage offenses of the 80's and 90's.
What? He is nothing like Rozier, DuBose, Jones, Brown, Phillips, or Green.
I think what he's saying is Imani Cross would probably have a more prominent role, or, have a better opportunity to succeed, in a power run offense. You're right in that Cross is nothing like Rozier, Jones or the other guys you mentioned. But, I don't think that was what NUinID was saying.
That said, I don't know if Cross would've been a great back in those other systems. Just so many variables at play there. I think another offense might lend better to his skill set, but, he's clearly being held back for some reason. And as other people have mentioned, this is the second staff in a row to feel the same way.
My opinion is he doesn't have great lateral quickness and it sounds like he's not the best pass catcher, so his role is somewhat limited. I also think the staff wanted to create some consistency in the run game against USA as well as boost Newby's confidence, and I think they succeeded in both of those areas.
Cross does what's asked of him and is a good player, but, sometimes I just wonder if this was the right place for him to go? The previous staff clearly saw something in him they liked, but his body type and abilities don't even really make sense for what the previous staff was looking for IMHO. Just kind of an interesting situation.
