That trio (20/93/24) was really good at the start of last season, but not so much this season. 20 and 93 love to carry the puck up the middle or left side of the ice, and Kakko doesn't hang with them on rush zone entries. If Kakko brings the puck up ice, they don't really support him, so he always gets angled into the boards by the blueline and either turns it over, or has to dump. 93 is soft on the cycle in the o-zone, and they prefer to keep 20 net front, so that line really can't get a cycle going when they do dump it in.
At this point might as well just leave Kakko with Cuylle. Bonino is where scoring chances go to die on that line though, and if they need to with someone out, I'd rather they put Goodrow there.
