"That's what we've done over the years here and we're not going to try and change anything.
"Jacob is a big, strong running back, but we just hope we can get him out of the backfield," he added. "They have so much speed and quickness they can blitz you awfully bad. We're just hoping to get him a couple yards and hope he can get us a few more."
The Greyhounds' aggressive blitzes also create chances for big plays from Parker, but again, Valley's defense is a concern.
"We face a lot of eight- and nine-man defensive fronts," McClintic said. "He's (Parker) broken some long runs because we get him past that first wave and get him one-on-one in the secondary.
"The big trouble with Valley is that they can track you down better than most people once you get in the secondary."
The Wildcats have attempted just eight passes this season, completing four for 151 yards and three touchdowns. Valley is led offensively by running back Keyshawn Payne's 496 yards on 40 carries. Payne also had seven scores.
Quarterback Raeshawn Breckenridge has 187 rushing yards and five TDs, while Dante Wilkerson has contributed 156 yards and three scores. Wilkerson also had a pair of receiving touchdowns. Drew Bowen leads the Greyhounds with six catches for 193 yards and two scores.
