"Probably just the coaches wanting me to get more reps with the 1s," Booker said, per Mike Klis of KUSA-TV in Denver. "Felt good about it and just continuing to go about the work."
The Broncos made it clear how they feel about Hillman this offseason. While furnishing Anderson with a four-year, $18 million contract -- including $10 million guaranteed -- Denver handed Hillman just a one-year pact worth $2 million.
Seen as an ideal fit for Gary Kubiak's one-cut, zone-blocking ground attack, Booker is going to see plenty of snaps this preseason. By his account, he already feels at home with Denver's playbook.
"I couldn't have fell into a better spot, landing here," Booker said Saturday. "One cut, zone system. I feel good about it every time we've got a run call play, I just one jump cut and go. Get downhill fast."
Anderson remains the obvious workhorse in the Rocky Mountains, but Booker has a realistic shot to emerge as Denver's No. 2 runner by Week 1. Maybe even sooner.
