Until Ballard gets his average above 2 yards per carry I wouldnt put a whole lot of faith in him. Decker doesn't get a whole lot of work between the 20's, that all goes to DT, but he is Peyton's favorite endzone target, (its also worth noting that Manning lobbied for the Colts to draft Decker, Peyton is a pretty big fan of that guy). Oh, and the Chargers secondary is overrated at best. Only 4 passing td's to WR's through the first 4 games? Good on ya Norv, but as soon as they face a QB on a mission and a receiving corps with some talent, they get blown up for 4 td's in a single game. (Matt Ryan had something like 4 passing td's too when they faced SD, but they were to Gonzalez and I think even Jaquizz got one, so thats not all on the secondary) Decker is worth the flex spot imo.
