First up, the Falcons secured the 19th position in the 2010 draft; Texans get the 20th spot via coin toss. In the middle of the draft one spot may not matter a whole lot, but with the loss of their 2nd round pick, I think every spot does in fact matter.
NFL.com analyst Bucky Brooks has put together his latest mock draft, which has the Falcons taking a linebacker.
19. Atlanta Falcons
Navorro Bowman, LB, Penn State
Mike Smith needs a playmaker at the weak-side linebacker spot, and Bowman’s athleticism makes him a perfect fit in the Falcons’ scheme.
I do not know much about Bowman; I think it is critical for the Falcons to get help on the d-line and in the secondary. If DT Peria Jerry is expected to make a full recovery, the Falcons could go in a different direction, but I think the first pick has to be an impact player on defense that can start right away.
The official Falcons site has an article with some quotes from GM Thomas Dimitroff and Head Coach Mike Smith. Nothing really earth shattering, but worth a read during the long buildup to the draft.
