If there are still questions about as the Broncos’ starter, the third-year quarterback is doing his best to answer them.
On the Broncos’ first drive against the Cowboys Sunday, Siemian marched Denver down the field and then found for a 10-yard touchdown pass over three Dallas defenders.
The score gave Denver an early 7-0 lead.
