Early year keeper suggestions. Fantasy football?

Tough call between AP & the 1st and Charles & the 3rd. I'd have to go with AP though. He's the biggest lock there is for a strong season in the Fantasy Football these days. I'm really high on Charles too, but he does have a less extensive track record than AP. Not only that, but you have to think if you decided to keep Charles, you probably wouldn't have a great pool of players to choose from with the 1st rounder anyways. Certainly wouldn't take Bradshaw, he's a dropoff from AP and Charles clearly.
