I really like Burleson and think he is getting the shaft in Minnesota, unless they are going to match any offer. The guy was injured last season and by the time he was recovered they had added Koren and he didn't see the field as much as he should have. I think with Nate on one side and Koren on the other, with Williamson as a third, they would be in great shape, not to mention the depth of Travis Taylor, who I thought played well last season. I think his fantasy production would be limited, though.
However, if the Texans were to sign him, I really like his fantasy potential. Andre is the guy on the other side that will be drawing more attention than Koren would, and that would leave him plenty of room to work.
Edited to add: A high third for him would soften the blow a little bit. Like someone else said, better the Texans' third than the Seahawks'
