The vast majority of teams have a mini camp either May 4-6 or May 10-12. A few do it May 11-13. The only 2 teams tha don't have a mini camp in May are ... Houston (June 11-13) and Denver (July 9-11). I'm wondering if there's a reason why we do it later than everyone else. Have we always had mini camp that late (comparatively) or is that something Kubiak brought over from Denver? Here's a link to the mini camp schedule. http://sports.espn.go.com/nfl/news/story?id=2857041
I am pretty sure the Texans have a rookie mini-camp either this upcoming week or the week after. Most teams have a rookie mini-camp in May and regular mini-camp in June.
The Texans will have OTA's (basically practice with out pads) starting May 16. They'll go five weeks with a Mini Camp at the end.
