Willis has shown increased comfort with offensive coordinator Bobby Slowik's concepts during the first two weeks of training camp and has been stacking up positive performances during practices, David Furones of the South Florida Sun Sentinel reports.
After joining the Dolphins in March on a three-year, $67.5 million deal, the fifth-year quarterback is heading into his first season as a full-time NFL starter. Willis has limited his mistakes and has been able to build chemistry with a mostly unproven receiving corps during OTAs, minicamp and now training camp, but the 27-year-old will get his first real test this week. He's set to receive extended reps against the Commanders defense in a joint practice Wednesday, and he could be in line to play a few drives against them in the preseason opener two days later.
