LAWRENCE, Kan.(AP) -- Itching to compare unbeaten Kansas with the
2007 team that rolled up 12 victories and vanquished Virginia
Tech in the Orange Bowl? Don't do it, says coach Mark Mangino.

The Kansas coach is seeing too many little mistakes and too much
of a leadership vacuum with this team.

"I don't now how many games this team will win," Mangino said.
"This team has a completely different personality than the 2007
team. ... That 2007 team had a little bit more maturity. If you
eliminate (Todd) Reesing, (Kerry) Meier and (Darrell) Stuckey
and (Jake) Sharp from the equation, it's really not a mature
football team. Those four guys kind of lead it and pull it
along, where we had a bunch more guys, leadership guys,
especially on defense (in 2007)."

A 44-16 victory Saturday by the No. 22 Jayhawks over undermanned
Duke may offer hints, and not just the two-play, 87-yard drive
the Blue Devils pulled off on their first possession.

Kansas' mistakes were evident, especially an uncommon number of
dropped passes. Todd Reesing's 338 yards would have approached
400 yards if Dezmon Briscoe and Johnathon Wilson had managed to
hang onto a couple of perfectly thrown spirals.

As the Jayhawks were stuck in a 7-7 deadlock against an ACC team
they were favored over by 22 points, Kansas failed on a
third-down play and Reesing kicked at the turf in frustration.

Although the Jayhawks eventually got rolling, the Blue Devils
hounded Kansas' offense much of the game.

Reesing agreed it's too early to start making comparisons with
2007.

"We did have a strong senior class that year, and we did have
some vocal guys on defense, which is something we may not have
as much this year," he said. "I think we need some more guys who
step up vocally and let some people know they're out there. It's
early. We've got time to improve."

This week the Jayhawks wrap up their nonconference schedule by
hosting Southern Mississippi. But perhaps the greatest concern
is whether this team is ready to venture into the tough
neighborhoods of the Big 12.
