As if we should have ever doubted it, the Minnesota Vikings will start All-Pro comebacking running back Adrian Peterson Sunday against the Indianapolis Colts in his return from missing three months due to meniscus surgery in his knee. The issue all week for those who own Peterson is determining how much playing time he will get in the game and also how effective he will be coming off of three months of inactivity. Reports are indicating Peterson will not only start but also could get the lion's share of carries over the incompetent Jerrick McKinnon. While McKinnon will still be the third down back due to his solid receiving skills, Peterson is likely to be the prime first-and-second down guy going against a soft Indy defense. Of course on the flip side, the Minnesota offensive line arguably is the WORST in the league right now that has acted like sieve against opposing D-lineman. Also throw in the fact Peterson looked a step slow out of the gates this season (no shock given his age and wear-and-tear) and you have plenty of reasons to look elsewhere this week. This is truly shaping up as a boom-or-bust scenario with Peterson this week but given the fact he will now start and likely get a good amount of work, we lean on putting him in there as your RB 2.
