The Bay Rivers District football season opens on Friday with four schools playing non-district opponents. Here one key element to watch in each game.

 Bruton (home against Greensville) looking for replacement

With senior leader Scott Frazier sidelined for as many as six weeks by a knee injury, Bruton has huge holes to fill at wing-back and linebacker. Zach Uvodich is only a sophomore, but he’s a talented one and will be counted on to fill Frazier’s shoes. If he’s successful, the Panthers will be that much better when Frazier returns.

 Warhill (at Park View of South Hill) looking to stop the run

Warhill’s porous run defense improved significantly when Parker Osterloh moved to defensive end for the playoffs. After giving up nearly 450 rushing yards in a 50-33 loss to Jamestown in the regular season finale, the Lions gave up fewer than 380 in two playoff games – one a victory over Jamestown. Osterloh, a Virginia Tech commit, will look to pick up where he left off as a full-time starter at defensive end against a Park View team that gained 291 rushing yards on the Lions last year without him on defense.

 Young Tabb (at James Monroe) looking for stability

You can’t judge Tabb too much by its game at James Monroe if the Yellow Jackets are anywhere near as good as the team that ran roughshod over the Bay Rivers last year. But if highly regarded Tabb QB Dan Schiele – who ran for three TDs against JM last year – is a steadying influence for the young Tigers in Fredericksburg, that will be a good sign.

 Poquoson (home against Southampton) looking for a QB

Rebuilt offensive line. New running back corps. Defense. Poquoson is so inexperienced at so many spots that we’ll learn much about the Islanders at nearly every position. But from Eric Nixon to Tee McConnell to Chase Pinder, the Islanders have known for five years who their quarterback was before the season started. We won’t get an idea this year until junior Jimmy Pryce and freshman Trey Hicks get their prime time auditions against Southampton.
