Why watch: It will be a big test for the Seahawks' offensive line, which has undergone significant changes since the first preseason game. Seattle moved Justin Britt to left guard and elevated former backup Garry Gilliam to take Britt's old spot at right tackle. Additionally, it's Drew Nowak's turn to start at center after playing behind Lemuel Jeanpierre last week. That group in general and Gilliam in particular will have their hands full with Kansas City's defensive front. It's not exactly a soft landing for Gilliam, who went undrafted in 2014 and only began playing tackle as a senior in college. Now he'll make his first career start against reigning sack champion Justin Houston. Will he and the rest of Seattle's new-look offensive line hold up?
Did you know: Quarterback Russell Wilson will be returning to the place where his career took off. As a rookie in 2012, he played his way into a three-man quarterback competition with Matt Flynn and Tarvaris Jackson. After strong performances in the second halves of the first two preseason games, he made his first career start at Arrowhead Stadium. He completed 13 of 19 attempts for 185 yards, two touchdowns and no interceptions while adding 58 yards rushing on two carries. Two days later, the Seahawks named him their Week 1 starter. "It's a great memory," Wilson said this week.
