There were many who realized that Bronco needed to do things his way and allowed him to do that. They remained friendly and you'd see a lot of them at alumni day. Others who wanted to pine for the old days found themselves on the outs because Bronco isn't the sort to deal with that.
I agree that former players have earned the right to say what they want. However, it's good to pick your battles. LaVell isn't coming back and no matter how many want it to be so, Kalani is not LaVell and frankly in today's climate shouldn't be.
