What is happening to the Texans?

When everyone agreed that signing Arian Foster to a good long term deal and to let Mario Williams walk everyone had to take that in for a second but went along with it just fine. After that, everything the Texans have done during their management in free agency seemed to have not made any sense.
The Texans have many unrestricted free agents whose contracts have expired, only three or four of them

would have wanted more money in their new contracts that being in Mario, Arian and Chris Myers. When we signed Arian and let Mario go and retain Chris Myers that is the move that everyone understood and made sense. The problem is the Texans went on to sign Arian and then release former Heisman trophy winner Matt Leinart to create some more salary cap space. Well everyone saw that coming. Then the Texans released right tackle Eric Winston who has started over 80 games and who was still under contract for 3 years was cut for salary cap space which still to this day shocks everyone and does not make sense. The next day after those cuts free agency opened. The Texans still did not secure contracts for any of the following free agents and who are now all on the open market: C Chris Myers, TE Joel Dreessen, OG Mike Brisiel, OG Kasey Studdard, DT Tim Bulman, LB Tim Dobbins, CB Jason Allen, S Domininque Barber, WR Bryant Johnson S Quintin Demps. Ok you look at this list and realize ok now also add Eric Winston and you see 3 out of 5 of the starting linemen of the best offensive line in the NFL...what just happened to the Texans? Some people briefly speculated that the Texans where up to something big. That they where letting some of these guys walk to bring back Mario Williams. That was a brief thought. Now everyone is on the open market with other teams flying out our free agents now giving them offers we definitely can not get back players like Mario and Eric and if you still think so then you are really keeping up a false hope.
The Texans should have extra cap room after resining all their small name free agents to basic contract extensions and then creating cap space saved from last year by not signing Joel Dreessen because he is going to want starter money now and same goes for Jason Allen. Then the Texans also would not retain Jeff Garcia and Jake Delhome as they wont be needing their services next season. It was also widely understood that Jacoby Jones would be released to be given an extra 4 million in cap space after his unproductive season and horrible last memory it is hard to see him in a Texans uniform anymore after he hasn't panned out and it showed while Andre was gone.
Cutting Jacoby was one of the acting factors why it was also understood that the Texans would draft a legit number two wide receiver after the gaping hole in production was obvious during Andre Johnson's absence. The only problem with this whole thing is now that all those players are now on the market and out of everyone the Texans brought back it was just a lone Arian Foster without his offensive line, oh did i forget to mention they released his fullback that was still under contract for 2 more years? Yeah Lawerence Vickers? Yeah he is gone now, that two great epic blocking fullbacks in two years the Texans have gone and let go. I don't know what the Texans are doing or planning but the team that was regarded as the most balanced team in the NFL and was regarded among national media as "The team to beat in the AFC", the same media would consider the Texans to make a legit Super Bowl run, the same team with Vegas odds of 8:1 to make it to the Super Bowl. Well this team as of right now has serious holes. Everyone now needs to pray, and possibly every mock draft reworked for the Texans draft choice.
