ALLEN PARK -- NFL Network is reporting some Lions players are disgruntled by new coach Matt Patricia's rules and methods. And Glover Quin saw the report.

His response: Well, duh.

"Players that were here previously, I'm pretty sure a lot of them are like, 'This is tougher, this is different,'" the veteran safety said in the locker room Wednesday. "But that's always expected when you have a new coach. It's just the way it is. The personalities (between Patricia and Jim Caldwell) are completely different, so obviously the way things are brought about are completely different. It's just a part of it. It happens to every team, and you just deal with it.

"Your job is to go out there and play football, and be a good football player."

The Lions didn't have many of those Monday night, when they lost their season opener 48-17 against the New York Jets. And that has amplified concerns that have been percolating in Allen Park for a couple weeks now.

Yes, practices are harder under Patricia than they were under Caldwell. They were on the field more than two hours almost every day during camp, and sometimes as long as two-and-a-half hours. Caldwell's practices almost never lasted two hours, and the ones that did were always followed up by lighter, shorter workouts to keep players fresh.

Under Patricia, the Lions were in pads basically every day. There was more contact. And there was more running. A lot more running. When the Raiders and Giants wrapped up their joint practices with the Lions, Detroit stayed on the field to run more sprints.

And players are talking about it. Some have said they were "worn down" by the tough days in camp.

Patricia also has shaken up the schedule, sometimes going early in the day, other times later, and keeping players out of the loop. They sometimes don't know when they'll be practicing until as late as a day beforehand. For players accustomed to routine, that has been difficult.

And there are a whole bunch of new rules, according to the NFL Network report, which has rubbed some players the wrong way. It remains unknown what exactly those rules are.

"When you don't have the results, and when they're as bad as they were (Monday) night, you leave yourself very little leeway as a head coach," Mike Garafolo said on NFL Network. "Because your guys are going to say, 'Wait a minute, we're being run harder than other teams, we've got more rules than other teams, and we're not getting the results? At least in New England they get the results.

"Now Matt Patricia on his end, he's going to look at it and say, OK, well, who am I going to get to buy in here, and do I have to jettison the guys who aren't?"

We talked the other day on @gmfb Weekend about the #Lions’ veterans being unhappy with how hard Matt Patricia has worked them and all the rules in place there. Results like last night’s blowout loss to the #Jets could bring things to a head ... both ways. pic.twitter.com/wCImJnLFlg — Mike Garafolo (@MikeGarafolo) September 11, 2018

Quin said discord among players over a new coach is normal, and especially this one because the approach is so different from Caldwell's.

"There's a lot of guys in here, man," Quin said. "There's a lot of guys in the locker room. No way that everybody is going to be completely happy. That's never been the case. Even schedules we've had in the past, there's always complaints. It's just part of human nature.

"I don't know who they're talking to. Ask NFL Network who they're talking to. Like I say, there's always going to be differences and people are always going to have things to say. Our job is to focus on football and trying to win games. Everything is better when you're winning. If you're winning, you know, it's hard to complain. You're winning, so whatever you're doing must be working."

Quin was among Caldwell's biggest supporters right until the bitter end, then stayed away from the team until the start of training camp. He said he wanted to spend more time with his family rather than participating in conditioning, OTAs and minicamp. And then in the opener, his regular full-time role was scaled back. He is happy under Patricia?

"I'm here, baby," he said with a smile.

One player who says he likes Patricia's coaching style is Matthew Stafford.

"He's just a fiery, competitive, aggressive guy that is going to do everything he can to help us try and be successful," Stafford said. "And that's a great thing to have.

"For me, I appreciate it. I understand that we're doing everything we can to try and win. And you can't let any kind of message get lost in the delivery of anything. And that was the same way with previous coaches that I've had. One side or the other, so it's not something I'm too concerned with to tell you the truth. Just trying to go out there and play better."
