Mark Chapman, Osi Umenyiora and Jason Bell look ahead to the weekend's NFL action as the new season gets underway. There will also be action from Thursday’s curtain-raiser, in which the Kansas City Chiefs took on the Houston Texans. The Chiefs beat the Texans in a thrilling play-off game earlier this year, hitting back from 24-0 down to win 51-33. They maintained that momentum by going on to win February’s Super Bowl against the San Francisco 49ers, again thanks to another comeback.
