Canes have no interest in Kulak, especially because they could just sign Tanev instead... like you tried to do here

The cap penalties are included by default already (see 'Overages' in the bar with roster size & cap hit).

Apart from that, you've aggressively overpaid Desharnais, gotten too much in return for both Kulak & Ceci, targeted a goalie that's similarly liable to crumble in the postseason as Skinner, and done so while dressing a variety of players that either aren't ready or who've fallen below replacement level.

You might get a 4th for Kulak half retained from the Canes, but that offer is a bit much.
