I'm with Been...Walker is real light in the head, has a big mouth, is undisciplined and is easily distracted. If he could buy into "TEAM" instead of "ME", just shut up and execute his duties then yea...the Ravens would have a good corner and player.
As it is...having Walker is like skating on thin ice.
We see that he can be good...then we see the liability.
Can't have that weakness in the playoffs against the high caliber teams the Ravens will be playing.
