It’s probably because he took a step back. He’s no longer really doing as much with the team like he did the past 2 years. He supposedly took on a lesser role.
AJ/Nuk/DW4 are friends and with a Bienemy interview being forced on Cal this is the moment when Cal has to put on his big boy pants and decide if he's going to let the players decide who mgmt is, or and who is bringing guys in or not bringing them in.
Personally if I'm Cal, I get on the phone personally and tell him Caserio is running the football ops and who goes/stays is Caserio's decision and if DW4 cant live with it that I (Meaning Cal) will put DW4 on the block. If we (Texans org/Caserio) get a suitable deal then we will trade him. If not, he's going to be here until we (Texans org) get a suitable deal. So suck it up and deal with the new reality of who's running the Texans org. I mean it's not like we didn't just give you $160 mil when Easterby was/is here and you gladly put ink to paper.
