Makes perfect sense to me.
Currently, we have zero young prospects. We know we need to develop some, as does Danny Boy. I think Danny is perhaps planning a hockey-style 3-line team for next year:
The starters, who...um...start.
The bench, who continue to play their 15 minutes as a unit.
Then #11-15, including 2 draft picks, Erden, and the 2 guys signed to non-guaranteed deals, who will spend most of their time in Portland getting better and learning how to play together.
Genius...pure genius.
