BOURBONNAIS — The Sun-Times’ Mark Potash breaks down Thursday’s practice, the sixth of 2019 training camp:

Iron beating iron

The progress of the Bears offense in Year 2 of the Matt Nagy era continues to be difficult to discern against a defense that looks ready to hit the ground running. Khalil Mack tipped and intercepted a Mitch Trubisky pass in an 11-on-11 drill. Mack later batted a Trubisky pass at the line. Cornerback Prince Amukamara also tipped and intercepted a Trubisky pass, then lateraled to Kyle Fuller, who completed the Pick-6.

“I don’t think there’s another defense in the NFL I’d rather go against in practice every day,” Nagy said. “These guys fly around. They do different things. It makes us better.”

Piñeiro shines

After missing short on a 55-yarder, kicker Eddy Piñeiro kicked a 60-yard field goal to cap another good effort. He made 8-of-9 kicks — also hitting from 33, 33, 38, 42, 45 and 50 (with room to spare).

This and that

Former Bears tight end Zach Miller watched practice from the sidelines, mostly with fellow tight ends. … Trubisky threw short touchdown passes to Trey Burton and Allen Robinson in team drills. … In the isolated one-on-one, Chase Daniel completed a deep ball down the sideline to rookie David Montgomery, working against linebacker Joel Iyiegbuniwe. … Daniel also completed deep passes to Marvin Hall, including a 70-yarder vs. Kevin Tolliver. … Fans sang “Happy Birthday” to right tackle Bobby Massie, who turned 30 on Thursday.

Up next: Practice at 8:15 a.m. Friday at Olivet Nazarene University.
