Wide receiver David Boston agreed to terms on a contract with the San Diego Chargers on Wednesday.

Fantasy Focus

David Boston's signing with San Diego is a coup for his fantasy owners who have him in keeper leagues. Despite missing eight games last season with knee and foot injuries as a Cardinal, Boston can reclaim his status as one of fantasy's most potent wideouts. The fifth-year pro is joining an emerging offensive unit that offers one of the league's top backs (LaDainian Tomlinson), an improving young quarterback (Drew Brees) and an accomplished deep threat wideout (Curtis Conway). He won't approach his 2001 league-high 1,598 receiving yards because of Marty Schottenheimer's conservativeness, but he'll receive more red zone chances and probably double his career high of eight touchdowns. Grab him after the elite trio of Marvin Harrison, Terrell Owens and Randy Moss. -- Roger Rotter, Fantasy editor Check out ESPN's fantasy football for more news ...

The contract is worth $47 million for seven years, but there is a stipulation that voids the final two seasons of the deal, so the total payout is likely to be less. The total of the initial signing bonus and a March 2004 option bonus is $7.5 million and $4 million of the 2004 base salary is guaranteed. The contract also includes several stipulations that protect the financial exposure of the team if Boston, a two-time offender in the NFL's substance abuse program, is suspended for any future violations.

However, the contract pretty much guarantees him $12 million over the first two years. Boston will get a $4 million signing bonus and a $550,000 first year salary. He has a guaranteed $3.9 million base next season along with a $3 million option bonus at the end of the season.

Boston, whom the Cardinals elected not to franchise, had more than $7 million a year on the table from the Cardinals, who didn't want to guarantee much money with signing bonuses. Boston is considered perhaps the best player available in free agency.

The receiver recently weighed 243 pounds and is able to run in the 4.3s. He suffered knee and foot problems last season. He's squatting 400 pounds three months after having a patella tendon surgery.

Playing only half a season, Boston still finished with 32 receptions for 512 yards and a touchdown. In 2001, Boston had the best season of his career, catching 98 balls for 1,598 yards and eight touchdowns.
