What’s a catch? What’s not a catch? Who the heck knows anymore? But the latest installment of the NFL’s most confusing discussion came to Halas Hall on Thursday. Here’s what we learned.

Miller has empathy for Steelers’ James.

Miller was watching Sunday as James’ 10-yard touchdown catch in the final minute was overturned by replay review, turning a 30-24 Steelers lead into an eventual 27-24 loss to the Patriots. After having his own 25-yard TD grab reversed in Week 8 — on the same play on which he dislocated his left knee — Miller had a message for James.

“I feel for you, brother,” he said. “I don’t know where this is going or where it’s already been, but I feel like we probably need to bring in a little bit of common sense to this thing.”

Miller met reporters Thursday to be recognized as the Bears’ recipient of the 2017 “Media Good Guy” award, an annual honor presented by the Chicago chapter of the Pro Football Writers of America to recognize a player for his professionalism, respect and courtesy. Miller also shared an update on his recovery. He has begun doing some walking again in rehab after eight knee surgeries.

Still, Miller’s most compelling thoughts centered on the NFL’s catch/no-catch controversy. From his vantage point, he was certain James’ touchdown should have counted and equally adamant that the NFL needs to find a way to rectify its problems with the catch rule.

Simplifying the language in the rulebook could be a start.

“I don’t even know what the language is at this point,” Miller said. “I don’t think a lot of people do. I don’t even know if the rulemakers know what the language is. But they have it there in place and I think they’re trying to follow (the rules) as closely as they can. I just don’t know if it’s where it needs to be.”

Miller hasn’t watched the video from NFL senior vice president of officiating Alberto Riveron explaining the ruling on his non-TD. The Bears tight end insisted he has little interest in hearing the clarification.

“Give me my touchdown back and maybe I’ll listen to his tapes,” Miller cracked. “But I could walk him through it.”

The top two picks will square off Sunday.

So what is Mitch Trubisky’s take on Browns defensive end Myles Garrett, who was picked No. 1 in April?

“He comes off the edge with a lot of energy,” Trubisky said. “He’s really freaky so we’ve got to do what we do from a protection standpoint and just play our game. Try to tire him out.”

Like Trubisky, Garrett has been a work in progress. He missed the season’s first four games with a high ankle sprain and didn’t play in Week 8 because of a concussion. He has recorded a team-best five sacks but has only one in his last six games. Bears defensive coordinator Vic Fangio studied Garrett’s game leading up to the draft and had little trouble pinpointing what jumped out.

“It was his size, his speed, his quickness, athletic ability and length,” Fangio said. “He kind of had it all, I thought.”

The Bears offensive line is depleted.

Guard Josh Sitton (ankle) missed his second consecutive day of practice, which may put his availability for Sunday in greater jeopardy. Tom Compton (concussion) was limited. If neither guard is able to play Sunday, Cody Whitehair and Bradley Sowell would likely fill those roles with Hroniss Grasu filling in for Whitehair at center.
