I doubt an underproducting injury-prone RB that can't/won't run between the tackles will be a high-priority. Darren Sproles would be a better choice (and he returns kicks, not just an occasional punt, like Bush-but of course if he were made of glass, he would probably only do punts too).
Bush impacts a game a lot more than Sproles does. Don't get bent up on stats. Saints fans (and Payton) LOVE Bush, at least the knowledgeable ones do. We don't need his production as much as we need his threats to defenses. We have the 3rd-leading rusher from last year (once he started), a talented young WR group and a 3rd-down machine TE. Bush takes up a lot of preparation time because of how he threatens defenses with his big-play capability in the open field. He commands attention from defenders and causes matchup problems. The Saints are difficult to defend because Bush threatens the flat and gets single coverage for Colston and co.
Sproles is a good runner, returner and receiver but he doesn't open up the offense like Bush does. Bush's health is a concern, but cap room isn't. We've been rumored to have interest in Bush (not Sproles AFAIK) and it's for good reason. He adds more value to the team than any other potential FA not named Nnamdi imo.
Bush can't threaten a defense when he isn't active... which is far too frequently in his career.
I'm not getting caught up in stats, what I get caught up in is watching him run for -2 yards when 3 yards would have gotten the first down... and then bring the stats into it, and Sproles blows Bush away. Primarily the stat of where Sproles has missed only 1 game in the last 4 seasons while Bush has missed 20. Never mind the stats that say Sproles runs for 0.6 yards more per carry during his career and 2.3 yards more per reception, Sproles also returns kicks and is a full-time punt returner. Another stat not to discard, is that Reggie Bush's production has gone done every season of his career.
I don't like Bush as a runner but Rah wants our carries to go to big backs anyway. If we're comparing Bush and Sproles as receiving weapons, Bush is far more threatening and therefore superior. His durability is a legitimate worry and argument to make, but half our team got injured last year so no one is safe from that. If we're worried about Bush getting injured then what about our DTs, Bowers, Benn, Grimm, etc.
He probably is a better all-around receiver. But his injury history is lengthy and would be a big risk... and a 3rd down RB's job isn't just to catch passes. WIlliams had several HUGE runs last season on 3rd and long and running does come into play quite frequently... and in that respect, Sproles is superior.
Sproles and Bradshaw would be huge additions but I have a massive mancrush on Bush. He always seems to make big plays against us and he's a serious threat to opposing DCs. Olson has proven he can expand the playbook and make use of unique talents.
