Settle down Francis, er dansby21. That's just 3TP being 3TP.
Let me put a few of my explainations behind your list:
Everette Brown - He's a proven pass rusher at the collegiate level who could project to SAM. Not that different than a Clay Matthews, except Brown was more productive in college.
BJ Raji - He's a wide body DT and many believe the Texans need a wide body. Even though the Texans may not concur.
Maybin - See Brown, Everette.
Wells - He's a big back that the Texans need. They just won't take him with their first pick.
Cushing - A prototype SAM that's NFL ready. But, is he worth a first round pick?
Davis - This organization won't touch Davis.
Tyson Jackson - Would have made sense prior to the Antonio Smith signing.
Jenkins - He looks like the type of CB the Texans prefer. Or is he a FS? I think the Texans would have to consider Jenkins.
Jerry - A duplicate of Amobi Okoye. Not seeing this.
Ayers - A college DE who occasionaly stood up as a pass rusher. A late bloomer probably can't project as an OLB. Again, would have been more likely before free agency.
