Andersen is a very underrated defensive player, and that's exactly what we want from our backup C. I also believe I read somewhere that he has added weight. And I bet that if we sign him, we will go after a backup SF and SG and leave the roster at 14, in case we can upgrade the position which hasn't worked out. And if it's Andersen, we will sign a player like Brown for the 15th spot.
But I think Andersen wil work out pretty well. He shows some real hustle and effort out there, and him and Powe together on the court would just mean pure energy. This guy has a career average of 1.3 blocks in only 16.4 minutes per game. He is one of the best shot blockers in the NBA. How would you not want him? He's also very athletic.
And don't you worry about character issues. Danny knows exactly who has a reason and who is just a thug. And since Danny contacted Andersen in February before signing Brown, I can assure that he doesn't have severe issues. That being said, I would love to have him.
