Running the Tests

Za'Darius Smith signed his contract on Tuesday. He will line up against an NFL offensive line for the first time as a Falcon on Wednesday. Zero installation days. That is not a depth signing. That is a diagnostic test administered before the patient has been prepped.

The Falcons-Colts joint practices at Grand Park Sports Campus in Westfield, Indiana — today and tomorrow — are the single most consequential evaluation window of this preseason. Shane Steichen confirmed the Colts' starters will not play Saturday's preseason game at Lucas Oil Stadium. Kevin Stefanski confirmed the same for Atlanta. The two practice days are the game action for top-of-depth-chart players, which means the edge rotation taking reps against Indianapolis's starting offensive line today is essentially the group taking the field against Pittsburgh on September 13.

I described the compound fracture we identified Sunday — the feedback loop between the quarterback room and the edge collapse that makes each crisis amplify the other. Today is not about relitigating that diagnosis. It is about running the tests.

The Edge: What Constitutes a Passing Grade

Here is the evaluation framework for a position group that lost nearly every contributor to last year's franchise-record 57-sack season.

Za'Darius Smith, 33, coming out of a ten-month retirement — 70.5 career sacks, three Pro Bowls, a 2020 second-team All-Pro selection — is here because the Falcons called and he answered. The one-year, $6 million deal (up to $8 million with incentives) is a calculated bet, not a rescue mission. Smith played under Stefanski in Cleveland in 2023 and 2024, which means the coaching staff knows his pass-rush profile: power-to-speed conversion, an ability to win with leverage against bigger tackles, and enough scheme familiarity to plug into Jeff Ulbrich's front without a week of individual installation. The question is not whether Smith can rush the passer. He has 70.5 sacks worth of evidence that he can. The question is whether a body that has been inactive since October 2025 can summon the first step and the hand violence that made those sacks possible.

Watch the one-on-one pass-rush periods. If Smith wins two of his first four reps with an identifiable plan — a setup move into a counter — that is a passing grade for Day 1. If he is reaching, lunging, arriving late, the contract becomes an expensive insurance policy rather than a functional roster piece.

Around him, the evaluation is more layered. Samson Ebukam — 35 career sacks, facing the team he played for when he recorded 9.5 of them in 2023 — needs to demonstrate that his comeback from a torn Achilles has produced more than the two sacks he managed across 14 games in 2025. Azeez Ojulari, whose 22 career sacks are offset by two seasons significantly limited by injury, needs to stay on the field for consecutive team periods without a trainer visit. Zach Harrison, recently activated from the NFI list, produced 4.5 sacks in seven games last season and remains one of the few encouraging data points in camp — but seven games is not a rotation anchor. Brandon Dorlus, graded PFF's 10th-best preseason pass rusher after one sack and two hurries in 13 snaps against Denver, offers interior-to-edge versatility that Ulbrich's scheme can use in sub packages.

The failing grade is simple: if the Colts' starting offensive line handles the entire edge group without schematic help — without needing chips, slides, or max protection — then the pass rush is not a concern. It is a void.

The Quarterback: Tua Against a Real Defense

Tagovailoa's joint practice reps are the most informative quarterback evaluation of the preseason. His two series against Denver — 3-for-5, 22 yards, both drives ending in punts — were a data point against a team that rested its starter. Today he faces Laiatu Latu, who generated 8.5 sacks and 61 pressures in 2025, and the Colts' full starting defensive front. This is the first time Tua sees an opposing starting defense since arriving in Atlanta.

The passing grade is not about completion percentage. It is about processing speed on third-read progressions, pocket movement under interior pressure from DeForest Buckner, and whether the ascending practice trajectory his coaches have described translates against a defense that is not cooperating. Penix remains weeks from 11-on-11 clearance. Cooper Rush's 7-for-19, two-interception preseason debut has already answered his question. The evaluation is Tua, and the evaluation is today.

What Two Days Can Tell You

Joint practices are controlled environments — no game adrenaline, limited pad contact during most periods. They are not a perfect simulation. But they are the closest thing to game conditions that these position groups will face before Pittsburgh, and the personnel decisions that emerge from Grand Park will shape the first eight weeks of the season until James Pearce Jr. returns from suspension in Week 9. The fracture was diagnosed on Sunday. The treatment plan starts today.
