Because we haven't won, and Ireland deserves to have ppl 2nd guess his moves. He hasn't done anything for fans to simply say he has a proven track record, we trust him. Granted the Tuna probably made most of the big decisions while he was here, it still shouldn't protect Ireland from deserved criticism.
However this doesn't explain the irrational stuff some Dolphin fans are engaged in with right now. I don't know what happened to the Dolphin fan base over the last 15 years, but from personal experience I've seen it change, in drastic ways. It probably has more to do with the Internet age we live in. But it would be nice for ppl to show some class, and go after Ireland with the facts, not with their hurt feelings exposed with every word they speak and write.
