I am just speculating but what I think is happening is PHX is going to end up trading Bledsoe for a PF in a S&T (Greg Monroe for example). Dragic will slide back to the starting PG spot and either Goodwin or Green will start at SG or Green starts at SF. Another possibility is they sign a guy like Gordon Hayward or Evan Turner. The Euro guy they drafted will stay overseas until next year if Dragic opts out and doesn't re-sign with PHX, he could play either guard spot as a back up and Ennis & Goodwin could be the starters if Green leaves. The bench will consist of Len, Morris twins, Warren, Ennis and a couple of spot fillers.
I think the draft was in preparation for after this season in which if Dragic opts out that gives PHX $7M+ more in cap space for FA next year plus another $3.5M if Green doesn't come back.
Also worth noting, a lot of hype was given to the 2014 NBA draft class but 2015 looks to be even better with guys like Jahlil Okafor, Cliff Alexander, Myles Turner, Emmanuel Mudiay, Trey Lyles, Stanley Johnson, Carl Towns, etc. So if PHX ends up with more than the possible 2 1st rounders next year they could be sitting even prettier.
