Peterson,Turner,Forte or Jones- Drew?

I've got the #1 pick this year,but I'm just not sold on taking Peterson.He fumbles a lot,gets hurt easily and doesn't score all that much.I like Turner,but he doesn't catch a lotta outta the backfield either.Forte looks good on paper (does both,runs well AND catches ),but I'm not so sure about him and Jones-Drew has a weak offensive line in front of him.It's a tough choice this year.The Bears have the easiest schedule overall,but the Vikings have a very easy first 5 weeks.Peterson and Turner might be the best 2 picks overall,but I'm leaning towards Forte.Who should I pick and why?
