playing basketball/swimming, etc

[sunnycalifornia]

I am currently trying to bulk at 5' 11, 149 pounds so I'm trying to eat a lot, I'm on Rippletoes, etc. I have a question though, I play basketball around 2-3 times a week (pickup games, scrimmages, etc.) and I also like to go swimming occasionally and just play sports. Since all of these will help to burn calories, should I cut down on them or do I just need to eat more to compensate for the loss of calories? For someone who is bulking, can they really not do much physical activity other than lifting?
