Right. A stretch of 3 good games by Portis means Danny made a mistake taking Rozier over him.
Just like how because Perry Jones III scored 33 points in game once meant he was definitely part of the Celtics future.
It's official. Patience no longer exists in Boston. I'm holding my breath on Danny's draft decision until I get a larger sample size. I firmly believe though that Rozier's development will take time, which is going to be a problem with a good amount of fans because right now the mindset is,

It's not just a stretch of 3 games. I'm talking from draft day, Rozier was a bust for the Celtics to draft. Not saying he's a bad player but a bust as in a bad pick for the Celtics. Portis would have made an impact on this team because of a need. With no Johnson being signed at the point of draft, or Lee being traded for. Rozier personally I never see being a starting player for the Celtics. Portis had the chance to if not would be the starter for the Celtics. Sing at the time of draft Sully and Zeller on last year of deals, KO having one more year. Last year the Celtics drafted a starting point guard in Smart, traded for a back up point guard in Thomas. At the shooting guard we have Bradley and Young who we drafted to be a shooting guard. Plus the signed Turner to play the positions of 1-3. Plus Crowder who can play the small as well as the shooting guard.
Patience I have, but the draft of Rozier was just not a smart draft choice with needs of the Celtics. Yes we got Mickey who will be a great addition but the last thing the Celtics needed in this past draft was a point guard who doesn't pass the ball. Rozier average just 3 assist a game in college. Plus the argument could be made he wasn't even the best player on his college team, Montrezl Harrell who we could have drafted was the best looking player on that team.
I remember being p---ed that Rozier was taken at #16 for the Celtics for that exact reasoning that we had enough guards in the rotation as it was, but then I thought about it, and realized that perhaps Danny didn't want to draft for need but more for drafting the guy who had the highest potential. Remember that article about Kobe and the Celtics a few days ago? Even though the Celtics were very impressed with Kobe's workout because of his potential, they took Antoine over him in 96 was because they believed Antoine was more NBA-ready than Kobe was. To be fair, they were right. Antoine had an excellent rookie season and Kobe didn't light the NBA on fire his rookie year (though he showed great potential). Of course now it's abundantly clear they screwed that up.
I'm not saying Rozier-over-Portis will work out like say Kobe-over-Antoine would have, but I think Danny's mindset was taking care of the Celtics needs in the future rather than their needs now by drafting Rozier. That to me why explains why he drafted Rozier (thought he had better upside than Portis) and went on to sign Amir Johnson and trade for David Lee (On paper they took care of the Celtics current needs as bigs) even if it meant the kid would be spending most of the season in Maine. Remember, rumor had it Houston or Chicago was going to take Rozier if he had been available after the Celtics selection (He wowed scouts at the combine). Also, Danny's had some of his duds come from drafting guys out of need like taking Fab Melo and JaJuan Johnson so perhaps he thought it was time to draft the best potential rather than the best fit. It's not like the Celtics are in "win-now" mode. They are still re-building while also trying to see how the team currently shakes out. The Celtics have picks galore coming over the next few years and have all the time in the world to decide what direction the team will go. I mean, for all we know, Rozier will get his chance to start. Thomas and Bradley might not be who the Celtics have in mind for their future backcourt, but who knows?
For all we know, Danny was completely wrong for taking Rozier over Portis, but I think we won't know that for sure for a few more years.
