In writing notes for the Inside Slant, FoxSports.com writes that "negotiations also have not started with second-round pick Rey Maualuga."
It's pretty common that draft picks tend to sign late in the offseason -- like right before training camp starts. Last year, the Bengals officially signed five draft picks on the day players reported to camp: Jerome Simpson, Pat Sims, Andre Caldwell, Anthony Collins and Corey Lynch. Most of them had agreed to deals beforehand, electing to actually sign when they arrived to Cincinnati for training camp. The Bengals signed Kenny Irons, Jeff Rowe, Matt Toeaina, Dan Santucci and Chinedum Ndukwe a day before the 2007 training camp. The Bengals reported to training camp in 2006 on July 29 and on that day (or the day before), the Bengals signed Andrew Whitworth, Domata Peko, Ryan McNeal and Ethan Kilmer. To say that the Bengals, and other teams, wait until the 11th hour with a majority of their picks, would be an understatement.
However, "team officials foresee no problems in signing their middle- to late-round picks. It's the first-round pick though that continues to be a concern as the team looks to be preparing for a long standoff with Andre Smith."
