Greivis Vasquez (top-5 passer)/ Klay Thompson (top-5 3P shooter)/ Zach Randolph (top-5 rebounder)
Greivis Vasquez is an undeniably talented point guard, but I don't think he's better than the actual point guard Randolph's been playing with. A lot of the success the Griz enjoy is because of the underrated defense that Gasol provides, and the overwhelming defense they enjoy on the perimeter. On top of that Gasol is an extremely talented passer.
You've lost that defense, and won't get it back (there are only a handful of centers on Gasol's level defensively), and to my eyes you've lost the defensive edge on the perimeter and downgraded the talent of your point guard.
You can maybe recover with the picks coming up, but it's going to require lots of savvy and some luck.
