Bush was credited with 10 tackles and a pass breakup in the 30-28 win. Baldinger said he counted 11 tackles for Bush in just 40 snaps played.
And, as Baldinger noted, at times Bush, the 10th pick in this year's draft, looked unblockable.
"He was everywhere," Baldinger says. "I counted 11 tackles. Maybe it was more. "If you don't have your head up, he's going to strike everything that moves."
It was a good start for the former Michigan star. And it seems he's put the NFL -- or at least Baldinger -- on notice.
The Steelers traded their top two picks this year and a third-round selection in 2020 to the Broncos to move up 10 spots and select Bush. It's the highest they have drafted a defensive player since taking Rod Woodson in 1987.
"(He's just) everywhere, everywhere," Baldinger exclaimed at one point. "A nice, smashing debut."
The Steelers will be looking for more of that out of Bush when they return to preseason action Saturday night at Heinz Field against the Chiefs.
