"You can go play blackjack in Vegas and play at the $5 tables and play for a couple hours and make bad decisions and lose $100 and have some fun," Schwartz said Thursday at the NFL Scouting Combine.
"You go play at the $5,000 and $10,000 tables, you're making bad decisions, and you're walking home. You're not flying home. So I think you've got to add that into the equation. Not only is it an opportunity to get a great player, but you also need to make sure."
"We don't plan on being 'The Greatest Show on Turf'; we're going to build it like an outdoor team," Schwartz said. "We're going to be a big, physical team that can run the ball and stop the run.
"We need to be built to have to go up to Lambeau Field in late December and win a game. We have to be built to go into Soldier Field and win a game in December or January that could mean the division. The best way to do that - when the weather gets bad and the wind gets blowing - you have to be able to run the ball and stop the run.
"The one lesson I learned from Bill Belichick and Jeff Fisher is that if you can run the football and stop the run - if you're strong up front on the offensive line and the defensive line - you'll be consistent from week to week."
Newly hired Detroit Lions coach Jim Schwartz has been making the rounds, including checking on former Broncos defensive coordinator Bob Slowik. Slowik is expected to be the Lions' defensive backs coach, joining new defensive coordinator Gunther Cunningham.
"It is rare in this league to get to spend 10 years with an assistant coach as we have with Jim. In his eight years as our defensive coordinator, Jim has clearly put his stamp on that side of the ball. He is competitive, a tremendous communicator and motivator and in our opinion he has been ready for this next step for several years. I want to congratulate the Lions for hiring the right guy and he will be missed here in Tennessee."
The Lions are expected to interview Titans defensive coordinator Jim Schwartz on Saturday as they continue their coaching search.
