That's not a lot of models or firepower output for a 2000 pt. army Mkerr. And only 1 Land Raider? Those Lone Wolves must be pretty expensive. I would think most 2000 pt. armies in 5th Edition should have enough firepower to stall 1 Crusader pretty early on. I don't think its a critique of your list specifically, just that the Space Wolves look really expensive, especially at 2k points.
