McCall's justifications for the odd decisions seem pretty sound. There are a few things I can disagree with, but I can still see why he made the choices he did.
Also, I thoroughly enjoy getting these emails. Agree that they would be better served being monthly, but really appreciate that McCall takes the time out to send these updates. As has been mentioned earlier in the thread, they do improve communications, which has been a big complaint in the past.
Even more impressive is the fact that he takes the time to reply to responses. I sent one after the Jeffers signing, pretty much questioning how he saw that Jeffers would fit into the squad, and got a lengthy email back, detailing some potential uses, but also highlighting that he would struggle to be a 90 minute, two game a week type, etc.
It's not much, but it's a nice touch.
