Well, you know how they talk about guys being late bloomers. My take is that Sellars is the opposite, an early bloomer. His game was great for his age at the time of his draft, enough for him to be taken #30, but since then he has plateaued. He has improved some, but not dramatically like most guys since turning pro.
The one game he played in the NHL might have been his last. Hope he got to keep the sweater.
