what does the rest of your team look like? do you need a left wing back? tough to tell without seeing your full roster. if ihad to choose one of these two trades id take the perry richards trade. but id like to see your roster first.
I would say the first one. Burrows is having a great year. Spezza is healthy and playing better now. Niedermayer would give you defensive depth. I'm sure you could make an even better deal but if its between those I would go with that one.
