On the surface I do not like it for the Vikes but I will give some reasons that it could turn out good...
1-Some big time free agent WR's out there such as Bruce, Muhammad (led the league in Td's last year), Derrick Mason, Plaxico Burress...If you can get one of those...then that would help stop the bleeding
2-If you can't, then you use the 7th pick to get Mike Williams, Braylon Edwards, etc...if you do wrap up a good veteran WR, perhaps they draft a good cover corner like Pac-Man from WV.
3-Moss had been too critical of the team (saying they could never win a championship) and his hijinks had rubbed teammates the wrong way.
