http://www.sbnation1560.com/sources-obrien-leave-houston-bad-relationship-rick-smith/ Audio in Link. 1560 Radio host Nate Griffin says he has sources that state OB may be out due to rocky relationship with Rick Smith. Other key points from the audio if you don't want to listen: - Hard Knocks crew noticed they didn't like each other much - Rick forced Os on OB - OB wanted to roll with Savage for the year - Only free agent OB had input on was Lamar Miller (seems strange to me)* - Kubiak had more control than OB does - Smith didn't want to have another head coach with more personnel power than him again - OB's relationship with Smith would be the reason he left The Lamar Miller thing is strange to me. I don't understand why he'd be the only guy OB would have input on. Sounds like ass covering since Miller is the only one who has been decent.
