3. David Boston 2003 San Diego Chargers
Boston landed a mega deal from the Bolts, cashing in for $47 million for 7 seasons with $12 million guaranteed.
The amazing thing about the Boston deal is that he landed it after a 2002 season in Arizona in which he caught just 32 balls for 512 yards and one touchdown.
Boston cared more about his weight lifting career than he did catching passes, and in his only year with San Diego he snagged 70 balls for 880 yards and seven touchdowns.
Not worth the money in the least.
