Defensive Pairs - Natural Stat Trick
Pairings that Kleven is on are bottom 3 in defensive zone starts. Green relies on Chabot, Jensen, Sanderson and Hamonic to do the heavy lifting there. He is literally getting easier minutes than them. Kleven is also bottom 3 in offensive zone starts.
He's a rookie who's made some mistakes and is holding his own. Coach doesn't trust him too much in our own zone or the opponents zone because he's still working on both his defensive and offensive game.
He's literally a rookie that we're properly developing and the last thing we need is to throw a long-term contract at him when we haven't even seen what he can do with more development. He's played more than 19 minutes 3 times in his career. I'm sure he can become a top 4 defender, but there's a lot of development left.
