If rebounding is what you need, then you should do the trade.
Hickson will get you double digits nightly and Bosh? Well just last game he gave you 16 points and ONE rebound. He's got to get 19 the next game just to average 10.
you have to give and take according to your needs.
Holiday is just a tiny bit better than Lillard.
Yes looking at your team, rebounding is the weakness. Hopefully Jefferson comes back strong for you.
