2 keeper league. I have LeBron as one. Other options are Pau Gasol, Ibaka, or Marc Gasol. Who would you keep?

Based on age and the small roster size I'd keep Pau there. With only two keepers Pau's age probably isn't an issue and you'll have lots of time to draft a replacement. When you have 5 active slots you want the best possible value from each slot, and this year that's Pau (especially with your scoring categories).
