Some players talked openly about the grueling nature of last year's camp and a few expressed concerns about wearing down during the season. The Vikings finished with a 6-10 record.
"We're looking at (tweaks)," Childress said. "In terms of practice, overall schedule, the number of practices and then maybe a rest, or a breath or a weightlifting day. Sometimes you get as much from that, unloading mentally."
Childress' comments should be encouraging for those who believed the head coach would remain set in his ways and wasn't open to change.
Among the differences Childress could introduce would be a few night practices, something Packers coach Mike McCarthy used last summer in Green Bay. A main benefit, of course, is keeping the players out of the afternoon heat during two-a-days.
There is a possibility the Vikings will have home-and-home evening practices against the Kansas City Chiefs, who train within driving distance of the Vikings in River Falls, Wis. Last season, the Chiefs visited Mankato for an evening scrimmage.
As for the Vikings' exhibition schedule, they will open against the St. Louis Rams on Aug. 10 or 11 at the Metrodome. That will be followed by a nationally televised game against the New York Jets at Giants Stadium at 7 p.m. on Aug. 17. Fox will carry that contest.
The Vikings will then play at Seattle on Aug. 24 or 25 and against Dallas on Aug. 30 at the Metrodome.
QUOTE TO NOTE: "He's just got to keep pushing. He's a million-mile-an-hour guy. He didn't have a sack last year, but that was through no fault of his own. He's a highly-conditioned guy. He plays smart. ... He probably had three sacks where he had the guy wrapped up, but the guy steps out of it and he flushes it to somebody else. He just has to keep working at it. I don't fault anything about how he prepares, mentally or physically." — Vikings coach Brad Childress on defensive end and former first-round pick Kenechi Udeze.
