Kennedy was Broncos' second-round pick in 2002

The Lions added the aggressive, young safety they've seeking for years when they reached a five-year, $14 million agreement with safety Kenoy Kennedy that included a $4.4 million signing bonus.

Kennedy was a hard-hitting member of Broncos defense and considered the top safety in the free agent market. He's been a starter for the past four seasons.

A former second-round choice from the 2002 draft, Kennedy, 27, will work with Brock Marion -- Kennedy as the strong safety and Marion as the free safety.

The Lions also made their first move to help their offense by signing former Colts tight end Marcus Pollard to a three-year, $6 million contract that includes a $2.3 million signing bonus.

Pollard will join an offense that has been upgraded over the past two years with the additions of wide receivers Charles Rogers and Roy Williams and halfback Kevin Jones. Pollard, a former basketball player, is considered a great receiving threat.

Pollard only caught 29 passes last season, but he's usually been a 40-catch receiver. With so many options available for the Colts, Pollard didn't have as much receiving activity as in past year.

The 33-year-old Pollard didn't play college football. The 6-3, 247-pound former basketball player went to Steward County Community College and was signed by the Colts in 1995 as an undrafted player.
