The Texans have signed WR/KR Bethel Johnson to a 1-year contact.  He played in 11 games (2 starts) last season for the Vikings and he caught 9 passes for 156 yards (17.3 avg) with 0 TD grabs.  He also carried the football 4 times for 8 yards (2.0 ypc).  But the area that Johnson might help the Texans the most at is kickoff returns.  He returned 45 kickoffs for 1,054 yards (23.4 avg) with 0 TDs last season.  Johnson was a nice low risk/high reward signing for the Texans.
