Some notes from the first day of San Diego Chargers rookie minicamp, which was held in 90 degree temperatures at Chargers Park on Friday.

Law looks the part: At 6-foot-1 and 255 pounds, outside linebacker Cordarro Law made his presence felt. The Southern Mississippi product finished with 14 sacks in the CFL with the Calgary Stampeders in 2013, and signed a futures contract with San Diego in January. Now, the 25-year-old is fighting an uphill battle to make the final roster. Law batted down a pass and looked quick coming off the edge during team drills.

Watt at right guard: Third-round pick Chris Watt was touted for his versatility, with an ability to play all three interior offensive line positions. However, Watt was lined up at right guard at rookie minicamp -- the same position of Jeromey Clary, who is to make $4.55 million in total compensation in 2014. Watt lining up at right guard probably is not a coincidence.

Talent in the secondary: Although first-round draft choice Jason Verrett did not practice because he’s still rehabbing from shoulder surgery, a couple young defensive backs caught my eye during team drills. Arizona State product Alden Darby had a nice pass breakup over the middle, and so did Auburn cornerback Chris Davis. At 5-10 and 192 pounds, Darby looked fluid going through individual drills with the defensive backs. Davis, at 5-10 and 201 pounds, is stoutly built like a running back. Rutgers product Brandon Jones also made a nice break on the ball to pick off a pass during team drills. Jones was on the practice squad last season for San Diego.

Roll call: Verrett is wearing No. 22, and second-round draft choice Jerry Attaochu is No. 97. Watt is No. 65, defensive tackle Ryan Carrethers is No. 92, running back Marion Grice is No. 26 and receiver Tevin Reese is No. 84.

Excused absences: Offensive guard D.J. Johnson and Reese will not be at the rookie minicamp this week so they can attend graduation ceremonies. Along with Verrett, Grice did not practice because of a foot injury.
