Matt Cassel was sharp in the first half, going 10-for-13 for 102 yards, but the Chiefs struggled in the running game and struggled to finish several long drives. Trailing 14-0 after the first quarter, the Chiefs would finally cash in on a 10 play, 80 yard drive with a one yard run by Peyton Hillis.
Much of the focus this offseason has been the new offensive philosophy by coordinator Brian Daboll, and Cassel was deadly accurate in the new offense. But just two plays into the first drive by the offense, following a quick touchdown drive by Sam Bradford and the Rams, Jon Baldwin fumbled on a short pass and gave the Rams another short field to work with.
Bradford would take advantage, connecting with Danny Amendola just five plays later to put the Rams up 14-0 in just six minutes into the first quarter.
The Chiefs would rebound, with Cassel leading his team to two second quarter scores to pull his team to withing 17-10.
Jamaal Charles, still looking to shake off the rust from his ACL tear last season, had just three carries for 17 yards in the first half.
