The Dallas Cowboys stress “situational football” every year in training camp.The San Diego Chargers are no different.They are redoubling their efforts to be football smart in the wake of a 1-2 start that has seen them lose games in the final seconds. The Houston Texans kicked a game-winning field goal with no time left in the season opener, and last week, the Tennessee Titans got a touchdown pass with 17 seconds left to beat the Chargers.“We’ve done a lot of situational work here,” coach Mike McCoy told San Diego reporters. “That’s what games come down to, is smart players making good decisions when the game is on the line.”He was asked about running back Danny Woodhead’s slide to save time just before halftime for a field goal try against Tennessee.“I’m not saying the game was on the line at the half, but that’s a deal to where understanding clock management — of understanding the big picture of, ‘Hey, you’ve got one timeout; when is 5 yards better than x number of seconds?’ — that’s what wins games. If we continue to do that and everybody else learns from that and as a coaching staff we educate the players on situational football, we’re going to win our share of those close games.”The Chargers failed to run out the clock last week against the Titans, gaining one first down and giving the ball up with 2:05 to go.Gates vs. WittenChargers tight end Antonio Gates has 657 catches, seven shy of catching Ozzie Newsome for fourth-most on the all-time list for tight ends.
