I see what you're saying and it's probably true to a point, but not entirely. I was texting with a number of friends throughout the draft last night and a bunch of them were on the side of "let's just grab some guards and make a run at the weak East".
I just shake my head when I hear stuff like that.
Progress for this team will be marked by an increase in wins by about 12-15. That would be wonderful and it shows we're headed in the right direction. Young teams take a while to gel, look at Minnesota with Rubio, Towns, Wiggins, LaVine, etc... They have a very talented core, but only won 29 games this year. Something like that next season, along with strong seasons from Simmons, Saric, whichever stays of Noel/Okafor, and Embiid (I care about health more than stats with him) would give us all tremendous optimism for the future.
2017-2018 is when we make a jump. We'll add two more top 7 or so picks in an incredibly strong draft (especially at the PG position), plus potentially Korkmaz and have about 60M to sign FAs next summer. That's when we go from 25-30 wins to 45-50 and become a team to be feared for the foreseeable future.
I'm absolutely thrilled about this team's future and I feel better about it after BC didn't mortgage the future last night.
