I love the vision and passing ability I see from Anderson. The other thing is that he would complement our shorter guards nicely. Considering we have Rondo at 6'1 and Bradley at 6'2, Anderson could really help us out with his height and length.
He is also a great rebounder for his position. I think if we take a SF like Wiggins with our 1st pick, then taking Anderson with our 2nd pick could make sense. He would be a rotation PG/SG for us and would work well with Rondo or Bradley. Also Anderson gives us Rondo insurance in case he does not resign in 2015.
If we draft Exum with our 1st pick, then obviously Anderson would not be a need and we'd look elsewhere, preferably a defensive BIG.
