I have been a proponent of tanking in order to try and secure Wiggins or Parker. I think that they, especially Wiggins, give us the best opportunity to win future championships. That being said, there is no way on earth that this roster can lose enough to be in the bottom couple of teams this upcoming season.
Rondo
Bradley/Lee/Brooks
Green/Wallace
Bass/Humphries/Sullinger
Olynyk
Clearly we have a big hole at the Center spot as Olynyk is much more likely to be effective at the PF spot, but even with him playing Center, this isn't a "worst in the league" talent roster. This is probably a 30-35 win team. Considering there will be one or two of the "rest of the guys" that have a decent year and we are flirting with an 8th seed most of the season. That will result in us being mediocre for another long stretch.
You will see whether or not DA is serious about not tanking if Rondo and Green are on the roster. If Rondo gets traded, then it was lip service. If both, then we are truly in full on tank mode. Without them both, this team is a 15 win team.
