Mazi Smith was drafted #26 overall. That's a great deal different than being a top ten overall pick.
Since 2000 there have been 11 DT's drafted between 24th and 28th overall. This is Mazi's range. When you look at their rookie seasons, only one of them started more than four games, Chris Hovan.
Hovan is tied with two others for most sacks in their rookie season with two. The other DT's are Jerry Tillery and Sylvester Williams.
William Joseph and Devonte Wyatt are tied for most forced fumbles with one. Five out of the eleven have double digit solo tackles.
Kenny Clark, in his rookie season, had zero sacks, zero forced fumbles, and four quarterback hits. He would later go on to earn two Pro Bowl selections. Clark became the starter in his 2nd season and is still starting this season, his eighth.
Others like John McCargo, Jared Odrick and Jerry Peria had short careers, mostly as backups. Career-wise, all but two ended up with single digit sacks.
This is the productivity received from DT's drafted in the bottom third since 2000. It takes a few years to develop starting caliber DT's, even former 1st round picks. They typically begin hitting their stride around their 3rd season.
This conversation should really be saved until the 2025 season. For now, he is coming along nicely, let's be patient. Many Cowboys have been vilified too early in their careers only to develop into productive players later. I still remember some of the words and phrases used to describe Dalton Schultz, Dorance Armstrong, and Tyler Biadasz.
