Hak's teams were astoundingly consistent over the years. He was vilified because he did not win a banner. Week in and week out, year after year, his teams performed at a very high level. The progress they made in the second half of many years was not a consistency problem. In fact, I'd say his ability to meld his players into very strong teams was very consistent.
This year's team does not have a great deal of talent at forward. I still think they are well coached and are a team most other teams would prefer to avoid, but they will have to be lucky to go deep IMO. One thing's for sure: they are not good enough to take undisciplined penalties.
Edit: I meant to quote willy's post regarding consistency. I have my own consistency issues.
