Star running backs/QBs seem to get injured way more often than star WRs. Here's the first round of one of my drafts last year:
4. R. Williams
5. A. Green
IMO, the best pick (regardless of draft position) was Williams, followed by Harrison, Owens, then Alexander (could probably argue he was better than Owens).
I could be wrong on this (and it obviously depends on the scoring system), but I believe Harrison has scored more points than any RB/WR over the last three seasons (and the last 4 seasons). Having Harrison/Owens is honestly like starting a RB in one of your WR slots.
