Here's what Baltimore Beatdown says:
He will make a great complement for the sure-handed Derrick Mason and intense Anquan Boldin in the Ravens passing game. Once again, very surprised to see such a highly ranked wideout still on the board in this position, a pick that no Ravens fan can be disappointed with.
Aldon Smith in the first round and now Baldwin here. The Ravens are having a solid draft getting players at great values. It's hard for them to pass this up even with the supposed character concerns on Baldwin. Baltimore is a veteran locker room so I think if any team can handle a player with character concerns, it's the Ravens.
