The Houston Oilers are going to have to reload to find more receivers to play their run-and-shoot offense.

The Oilers, the NFL's most prolific passing team last season, left four receivers exposed as Plan B free agents -- and yesterday, three of them signed with other teams.

The biggest loss figures to be 35-year-old Drew Hill, whose final NFL season will be spent with Atlanta. Hill, the only receiver with four 1,000-yard seasons after age 30 and third in the league in catches last season, will make $800,000 for 1992, $500,000 as a signing bonus.

Hill will be rejoining his former coach, Jerry Glanville, who also took Houston wide receiver Tony Jones. Jones received a two-year contract worth $800,000. Houston also lost another receiver, Alex Johnson, who signed with New England after playing seven games for the Oilers last year.
