I think he WAS doing right by sticking with Siemien up until a week or two ago.  But by then it was clear Siemien's shortcomings were becoming a bigger and bigger liability, and a poor fit for trying to overcome weak OL play.  He should have been benched at halftime last week, IMO.  And if not then, to start @KC.  And if not then, at halftime last night.  

But Joseph just keeps stubbornly throwing him right back in there. I've liked Trevor, but ugh, it's just not working. And by the time VJ finally makes the change, the season will be lost. With the way our D was playing last night, that was a very winnable game. Granted, the WR's (except DT) were dropping everything. It wasn't all Trevor's fault. But a lot of it was. The 2-pt conversion was yet another example of locking into 1 WR. The first INT was a horrible throw. The 2nd INT was a horrible decision. On and on it goes.
