They're 10th best in the league in shots against, but have given up the third most goals. It's not a PK issue, either. They have a good PK and are one of the least penalized teams in the league. Bobrovsky isn't having a great year, but he's still doing better than either Reimer or Luongo.
they got a good group up front, they have Ekblad on the back end. I don't think they're far from being a contender (though, clearly, not on the level of TB that has such ridiculous depth everywhere), but they need a goalie they can have some confidence in.
