Niners come in at 15: "Some teams on this list have an inordinate amount of young starters; the 49ers aren't one of those teams. However, if you were to skip over the foursome of T Anthony Davis, WR Michael Crabtree, G Mike Iupati and LB NaVorro Bowman as only "pretty good" you'd be missing the forest for the trees. DE Aldon Smith showed he could be a dynamic pass-rusher last season, Chris Culliver played early and often at nickelback and RB Kendall Hunter is going to be part of a large group of committee backs that will also include 2012 second-rounder LaMichael James. This group has a few potential stars and, perhaps most importantly, very few young starters who started purely due to injury attrition."
