The issue as far as I can see with Westerman is that we paid a fee for him. I suspect if he had come to us in the usual way simply signing after contract ended at Cas then we wouldn't be expecting so much from him.
I'm not sure what we expect from him. Last season Radford seemed to allow him to play a more open role. This year with Pryce and Sneyd at the helm it appears to me that he has had to revert back to being a third prop at times. Thus redering him ineffective. Or at least not as effective as his skill set allows.
Add in an absolute mare in our biggest game of the season and I can see why some might be glad to see him go.
As for Abdul hes old enough hes big enough I'd expect him in the 17 most weeks next season. He needs a massive off season losing some of his muffin top, but he will either be rotting in the frankinstein team or at a DR club. Get him in the first team and developing off Mini and co.
