I have posted this in other teams involved forums and the main forum.
I feel this is a W for all teams involved. Admittedly I don't know much about Raptors roster or circumstances so please forgive me if I made a misstep along the way.
I feel this gives you a star player who has experience and can help develop your roster while potentially recruiting if kept happy. Gasol has good relationships with many players including just about every forgein player and my understanding is some foreign players are drawn to Toronto because setting makes them feel more at home. That is how got Turkey from Blazers. If this is incorrect please let me know and I apologize.
This also gives you a PG who showed flashes and potential in LA who can backup Calderon, if not mistaken he is 6'4 and can play some SG. Might be able to one day take over PG for Calderon.
Again I am just a fan of Blazers trying to have a productive conversation where get feedback, learn about other teams, and just have a good time. I do not mean to offend anyone or make poor assumptions. If I have made any please let me know and help me further develop my knowledge of the game and league.
