In the NASCAR race today Joey Logano was running second to Matt Kenseth and becoming frustrated by his inability to pass him for the lead. He solved the problem by hitting the leader's back bumper, causing Kenseth's car to spin out and wreck and putting Logano into first place. The announcers unanimously agreed that Logano was merely "doing what he needed to do to win the race," which he eventually did.
By that standard I guess Chargers' coach Mike McCoy should have brought a M1911A1 .45 caliber pistol with him to Lambeau Field and simply shot Aaron Rodgers dead. He would simply have been "doing what he needed to do" to win today's game.
