First, I expect Yak will end up back in juior.
1. Chabot & Sanderson are the only two defencemen who will be on the PP for a few yrs still, but Yakemchuk will be a good replacement at some time & eventually will be on a future PP.
2. He is big enough, has a long reach, strong enough & has a mean streal to also play on the PK, he blocks shots, he hits, he wins board battles & is a good enough skater to skate the puck out of his zone.
3. Not only will Yakemchuk play on both special teams in future he is going to be good enough 5 on 5 where he can use both those special team skills & strengths that will help his teammates be better. It will take him some time to get up to speed but so much to like.
I expect Ostapchuk could end up in Belleville but for how long will depend on him. In these preseason games Ostapchuk has shown a lot of good attributes & skillset for the kind of player this team needs. We can see he is close to being NHL ready, but IMO needs to get a little stronger & a little more aggressive but he is also going to be a good NHLer & help Ott win.
Kleven is going to be on that 3rd LD spot & he too has shown that he can break up plays with a strong hard hit, he can win board battles, he can block shots & I expect he will be on the PK. He's a good skater & can get the puck out of his own end he is a good passer & makes good reads & passes, he's not going to wow you but he is efficient with his play. I expect he will be a solid D for yrs.
Boucher will end up in Belleville & for his sake hopefully stays healthy for the entire yr & regains the kind of play he had going before his injuries. He has an NHL shot is a good passer & heady player who can change momentum with a big hit or hard wrist shot.
Yak, Ostapchuk, Kleven & potentially Boucher, four good young prospects built for the playoffs who can help the Sens be a much better team as they progress in their development.
