Todd McShay released another mock draft this afternoon, and it is full of surprises, especially in the top 10. (You can only see 1 through 16 if you don't have an Insider account.)
Here is what he has for the Titans:
30. Tennessee Titans: Darrius Heyward-Bey, WR, Maryland
Heyward-Bey is a bit overrated in our eyes, but his ability to stretch the field vertically will be enticing to a team like Tennessee, which is in need of exactly that kind of weapon.
I still don't think the Titans will take a receiver but pretty much every mock draft we are going to see between now and April is going to have them taking one.
He also has a second round with the Titans taking Duke Robinson, G, Oklahoma in the 2nd round. That is probably even more unlikely than taking a receiver in the 1st round.
