Csonka is a Hall-of-Famer, and Morris was outstanding.
But the wild card is that people tend to forget how good Jim Kiick was, how tough a runner he was around the goal line. This group doesn't have that third guy.
Good as Brown might be, we won't know for sure until he pads up; and if RW comes back at 195 lbs, forget about it.
It's hard to compare actual accomplishments with speculation, but the fact is that we don't even have the full complement of elements in place to even begin this comparison; but I'd be interested to revisit this after this season.
