Drop jacoby jones for louis murphy?

Murphy is a great play this week if he's healthy enough to go. The Texans are tied for last in fantasy points allowed to opposing WRs. They have already allowed 761 receiving yds and 4 TDs by WRs. Oakland has allowed one more WR TD, but is actually the #10 fantasy D against WRs. They've only allowed 240 receiving yds and opponents have only targetd WRs an average of 13 times per game (combined for all WRs)
