Thornton caught all four of his targets for 86 yards in Sunday's 33-30 overtime win against the Colts.
Thornton and quarterback Patrick Mahomes had struggled to get on the same page at times last season. However, the duo's chemistry was in fine form Sunday, as Thornton made up for a quiet Week 1. The wide receiver played 47 of the Chiefs' 80 offensive snaps in Sunday's overtime win and could continue carving out a larger role in coming weeks.
