Observations from Jets’ training camp on Friday:

Justin Fields had an excellent practice, moving around well in and out of the pocket while showing strong chemistry with Garrett Wilson and Mason Taylor at different points on a run of 12 straight completions.

The defense got some pressure on Fields, but was a little lax in coverage, with receivers consistently open.

Rookie wideout Arian Smith had an impressive day, catching a touchdown from Tyrod Taylor on a crossing route and making another play down the sideline on a deep ball from Fields.

Quinnen Williams (calf) and John Simpson (back) both missed Friday’s practice and will be out a week or two, though coach Aaron Glenn stressed both absences are precautionary. Malachi Moore also missed practice with an oblique strain. Running back Braelon Allen was back after missing two practices with knee soreness.
