Warning: total snap judgment based on no good information and just 3 seconds of footage viewed one time, BUT: I saw that short clip of Manning signing autographs at the Colts game, and just from that short clip I thought I saw a guy who was still very very uncomfortable moving his shoulders/arms independent of moving his entire torso and neck as a whole unit. Take Luck, and either groom him under one year of Manning or trade Manning to the Niners/Vikings/Dolphins/Redskins for picks.
