That's the best possible destination and cast for Okposo.
In fact, when ever I describe Okposo I always use Benn and Seguin as an example of the type of firstine that Okposo should play on.
He can't be the go to scorer or first option on a first line. If he's the 3rd wheel that would be the most ideal ace for him and the game he plays.
Here's the rub with Okposo, he's a bad 2nd or 3rd wheel. He LOVES handling the puck, he won't give it up once he gets it too. He also has very questionable hockey sense with brutal decisions so he is prone to a mountain of turnovers. It's quite amazing how many plays die on his stick. You don't get the nickname OkpoSUCK, SUCKPoso, Dumdum21 for nothing.
He's a puck hog and gets tunnel vision with the puck while also being a major defensive liability. Benn and Seguin would be like 'WTF' for most of the game until that one play where it works and he gets his ninja point. Tavares routinely got stuck down low in the offensive zone expecting a pass or simple cycle that never comes because Okposo is too busy over handling the puck with his dipsy doodle toe drag crap and then eventual turnover. Okposo is a bad fit to pair with a star player because he thinks he's the star player on the line and doesn't defer puck handling duties.
Okposo is more suited to drive the bus for his own line on a lower line where he can handle the puck to his heart's content. Make sure he's paired with 2 defensively responsible wingers. He always had success with Nielsen and Bailey because they were ok with deferring to him. He's also a puck hog on the PP too, so be aware of that.
He needs to get it out of his head that he's a skill finesse forward. When he simplifies his game, he can be a major force. Those flashes are less and less. He'll be on fire for 10 games and then disappear for the next 10.
