Wide receiver Marquise Brown was among several Kansas City Chiefs who left practice with an injury Tuesday, when the nearly 2 1/2-hour workout was conducted in temperatures that produced a triple-digit heat index by its conclusion.

While Mahomes was able to make it work last year, it was far from a free-flowing offense, often stuttering and spluttering along, and the hope was that with a full group of weapons, the Chiefs of years ago might make a return with the deep ball coming back.

The Kansas City Chiefs have a lot to work on in training camp this year. But there is one question that fans and a lot of problems want answered from the Chiefs on the offensive side of the ball.
