Game No. 3 of the four-game NFL preseason schedule is the one in which starters stay on the field the longest. Lucky for Chiefs fans, the team’s penultimate exhibition takes place in Kansas City. Tonight’s opponents, the Seattle Seahawks, were in the Chiefs’ position in 2001 when they traded for a backup quarterback, Matt Hasselbeck, ready for a starting role. Chiefs fans would probably be happy if Matt Cassel, Tom Brady’s understudy in New England, developed into another Hasselbeck, a three-time Pro Bowler. Kickoff at Arrowhead Stadium (1 Arrowhead Drive, 816-920-9400) is at 7 p.m. Brokers are offering seats for as little as $10.
