I'm not surprised. The season is so long. A 10-11 start is more or less equivalent to a 1-1 start in football or a 5-5 or 5-6 start in basketball.
Tons of time left. They're not out of the woods yet. But certainly anyone who thought they were done radically underestimated them.
The best part is that the offense hasn't even really clicked yet. Once that does (and it will) look out.
