Dekker, Harrell, Andrew Harrison, Dakari Johnson.
I echo what somebody else said earlier about Dekker and Rozier being on a similar tier, so you use the pick on a position of greater need.
I always liked Harrell, and using second round picks on role players from Kentucky seems like good value, since those guys might have had much more illustrious careers as featured players on less talented college teams.
I think Dekker would have played more than Rozier this upcoming year. Actually Dekker really intrigues me. But I've come to think that Rozier will get closer to an All-Star game than Dekker.
Edit: Also, while trading Bradley for a big is fun, it would equal a pretty big hit to our perimeter defense. Trading Smart for a bigger fish ditto (even more so). This pick allows a trade without sacrificing that aspect of what made the Celtics a good team the second half of last year...
I like Dekker but he shot himself in the foot by skipping the Celtics workout.
He also can't create his own shot very well, streaky shooter (give him props for some of those clutch buckets he made in the tourney but also was horrible vs Duke in the finals- puzzling) and is not very good in one thing, decent in many.
Danny went with upside and potential when he drafted Rozier. His stats should of been better but in the end he carried Louisville to the elite 8. On the Celtics squad with potentially less traffic under the rim, Roziers game can flourish. Rozier shot the 3 at a very good rate in year one (37 percent) but only 30 percent in year 2. So he can shoot, but needs to take quality shots. In addition with him not being double teammed from the start in the NBA, he can concentrate on shooting the open 3's - his efficiency can increase.
This is what I think is going through Danny's mind
