Plays that defined the season: No. 4

KANSAS CITY, Mo. -- The Oct. 6 game between the Kansas City Chiefs and Tennessee Titans was scoreless in the first quarter when Dustin Colquitt’s 40-yard punt bounced off the foot of Tennessee’s Damian Williams and caromed into the end zone.

The mad dash for the ball was won by none other than Chiefs rookie cornerback Marcus Cooper and the resulting touchdown gave the Chiefs a 7-0 lead in a game they would eventually win 26-17 to raise their record to 5-0.

Cooper had joined the Chiefs only a few weeks earlier, off waivers from the San Francisco 49ers at the start of the regular season. The fumble recovery was not the only contribution Cooper made during the season. After quickly becoming Kansas City’s third cornerback, Cooper had three interceptions and other than a horrible three-game stretch toward the end of the season played better than the Chiefs had a right to expect.

The Chiefs did a nice job of taking the castoffs from other teams and turning them into necessary components. Cooper was the prime example. A converted wide receiver, Cooper played just two seasons of defensive back in college at Rutgers but the Chiefs saw enough in him to not only claim him when the 49ers waived Cooper but also use him regularly.

Other players who joined the Chiefs off waivers at the start of the regular season were tight end Sean McGrath and cornerback Ron Parker, both from the Seattle Seahawks.

Tight end was a position for the Chiefs that was often plagued by injuries. McGrath was often the only healthy player at the position. He wound up leading Chiefs' tight ends with 26 catches and also scored a pair of touchdowns.

Parker helped preserve a one-point win against the Dallas Cowboys in September with a sack and a forced fumble. He also was a standout in the final regular season game against the San Diego Chargers when the Chiefs rested many of their starting players.
