Had a segment on his show today where he went through why this trade makes sense. Basically says Lillard is a better fit for Lebron because he actually plays every night (AD missed more games this year than Dame has in his entire career) and in addition, Lillard can actually lead the offense. So when Lebron rests, the Lakers won't fall apart allowing Lebron to scale back his mpg and take more rest days. And Davis is obviously a big enough star that it might actually entice Portland to move on from Lillard.
At first, I was like that is crazy, but it does actually make sense on some level. They make around the same amount so it could just be a 1 for 1, but there are other pieces that can be included.
