Chargers assigned the original-pick tender to restricted free agent WR Danario Alexander. The move is surprising and may indicate San Diego's new front office isn't thrilled with Alexander's knees. Rather than tender Alexander at the first- or second-round level -- and protect themselves with draft-pick compensation if a team tries signing him away -- the Chargers have left themselves open to being pick-pocketed. Alexander was originally undrafted, and San Diego would receive nothing in return if a club signed him to an offer sheet and the Bolts failed to match. Alexander is 24 years old. In a nine-game stretch last year, he racked up 37 catches for 658 yards and seven touchdowns -- numbers that extrapolate to 66/1,170/13 if prorated across 16 games.
