What happened: He closed Week 1 at 15 of 27 for 207 total yards and three total touchdowns as his team opened 1-0. The score turned his return from a camp storyline into an immediate result on opening weekend.

Why it matters: That matters because any early production from Mahomes' return changes the read on September quickly. It also moves the focus from whether he could get back on the field to how fast he can look like himself again.

What to watch: Week 2 will show whether the same workload and scoring pace carry over. Midweek participation will be the next marker on how settled his return looks.
