To Tor - Gasol
To LAL - Bargnani + Calderon
LAL gets a great backup PG that is capable of starting if Nash gets hurt in Calderon. Definitely a major improvement over Blake.
Also, now that Howard is with the Lakers i think they need a big that can shoot(Bargnani) to keep the defence honest. I think Bargs right now would be a better fit with the Lakers than Gasol.
Raptors on the other hand gets a great player, a great low post guy in Gasol.
