I'm saying that committees and injury replacements tend to lead their teams to wins and playoff success more often than star backs. Lynch is the only star back to lead his offense on a recent Super Bowl champion, and he, again, was a free agent for a team that wisely spent their top draft picks on other positions. And Bell really seems to be the only star back on a team with real championship hopes right now, and the team still makes the playoffs and wins a postseason game in a year where he barely played.
This isn't even going into the fact that drafting a RB high leads to having a star. The success rate for highly drafted RBs seems very low (0% in the top six, and maybe one, Gurley, in the top ten) since AP in 2007. Going back further, there aren't any other success stories for backs drafted this high all the way to Jamal Lewis.
So, I'm saying drafting a back this high is higher risk than other positions. And I'm also stating that even if Elliot becomes a star, which I have stated I believe is a good chance, the reward is not worth it because team success is not dependent on a star back. Rushing success isn't even dependent on that.
Those are my points boiled down. I think Elliot is a high, unnecessary risk for us, but if we were to draft him, I would love him and root for him and hope that our team's perceived lack of huge needs means his success will go hand-in-hand with our team's success, against all odds.
