Who should the Celtics target after the 1st pick?

The Celtics obviously have the number 1 pick in this year's draft and it is presumed that the Celtics will draft Fultz with that pick. So who should the Celtics target with their other picks in the draft? The Celtics currently hold picks 37, 53, and 56 in the second round and there are a handful of players that they should look to target. 

1.  Frank Jackson Duke PG - If Jackson is by some miracle still available when the Celtics draft at 37 then they need to draft him. In my personal opinion this kid is easily a first round prospect who could go in the early to mid 20's. However, I am in the majority as most mock drafts have him going in the mid 30's.  I know that the Celtics are currently loaded at the PG position and with the addition of Fultz the G position gets even deeper for this season. However, in the years coming Bradley, Smart and Thomas are all free agents. The Celtics will most likely have to let one of them go and Jackson could replace them in the rotation.

2. Tyler Lydon Syracuse PF- Lydon has been plummeting down draft boards and is now projected to go early in the second round. If so, Lydon would fit perfectly into the Celtics offense as he is a solid rebounder and can really stroke the ball from the 3 point line. Last season at Syracuse Lydon averaged 13.2 points while shooting 40% from three and grabbing 8.6 rebounds per game. Lydon also showed an ability to protect the rim as he blocked 2.6 shots and recorded 1 steal a game. 

3.  Dillon Brooks Oregon SF- Brooks is projected in the middle of the second round and is definitely a player the Celtics should target. Brooks is a pure offensive talent and he hit clutch shot after clutch shot this season. I think he's definitely someone the Celtics should take a shot on as he could provide them with some much needed offense off of the bench. 

4.  Cam Oliver Nevada PF- Oliver is another significantly underrated prospect in this year's draft and is a player the Celtics should target. Oliver is 6-8 210 and a great athlete who showed significant improvement in his 3 point shooting this year. Oliver is a great rebounder and could help curb the Celtics rebounding woes.  

5.  Nigel Hayes Wisconsin SF/PF-  Hayes has always been a great defender and showed at the combine that he can shoot the ball fairly well from the NBA three-point line as he shot at least 40% from every spot behind the arc. Hayes is one of those guys that teams should take a chance on. Last year, I thought that Hayes was an end of first round talent and while he regressed some this year I still think that talent wise he should be drafted and I think the Celtics are the perfect team to take a chance on him. If Hayes can turn into a solid three and D player he could add to the Celtics' depth.
