How many first round draft picks are expected to not have much of an impact? Especially on the d-line, where, as many here said, his job is to just "plug up the middle" and "he's not going to have many stats, there's no stat for just taking up space". That doesn't take a whole lot of technique.
First round picks are expected to show something, don't have to start, but if you watched Mazi all this year, he's done basically nothing when he's in there. Most of the time he's pushed back, at best he manages to stand his ground against average o-linemen.
Now I'm perfectly willing to give him time, not everybody develops at the same rate. He may yet turn out well.
My problem is not so much Mazi himself, it's that Dallas took him in the first round knowing that in college, he showed little or no pass rushing ability. This isn't the 1950's, teams throw the ball more often. Your NT has to be able to put on some kind of a pass rush. Remember Jay Ratliff? In the 6 years he played all or nearly all the games in a season, he had 24 sacks. And he was a 7th round draft pick.
But at this point, Mazi has been a disappointment...
