Just like that, the MHSAA football season is one-third over. And after this weekend, teams will be cruising into the midpoint of the regular season. 

Don't let it pass you by. We're entering the thick of league races, Homecoming and rivalry games. The toughest part can be choosing which to watch. 

See below for some of the best options near you. And remember to visit the MHSAA Score Center for updated scores and standings.

(All are tonight unless noted. Go to Score Center for additional dates and kickoff times.)

Bay and Thumb

Flint Powers (3-0) at Saginaw Nouvel (3-0)

This beats out some pretty strong league matchups because of a few hard-to-match circumstances. Both are undefeated, yes. But both also are reigning MHSAA champions -- Powers won Division 5 last season and Nouvel was Division 7. Both have already survived close calls, but are surging behind solid defensive efforts -- both teams are giving up roughly 11 points per game. 

Others that caught my eye: Croswell-Lexington (3-0) at Capac (2-1), Bay City Western (3-0) at Saginaw (2-1), Marine City (2-1) at Clawson (3-0), Goodrich (3-0) at Montrose (2-1).

West Michigan

Lowell (3-0) at Muskegon (3-0)

These two have been in the conversation for best game in the state just about every week so far. That's the product of loading up tough nonleague opponents before expected championship runs through their respective conferences. Lowell is a slight favorite in the O-K White, and Muskegon is a little bit more in the O-K Black. But this game might indicate something even bigger -- the eventual frontrunner for the MHSAA Division 2 title. 

Others that caught my eye: Allendale (3-0) at Comstock Park (2-1), Hudsonville (1-2) at Grand Rapids Christian (2-1), Zeeland East (3-0) at Grand Rapids Forest Hills Central (3-0), Cedar Springs (3-0) at Zeeland West (2-1).

Mid-Michigan

Saginaw Swan Valley (3-0) at Alma (3-0)

Two teams kept Alma from winning the Tri-Valley Conference Central in 2011, and the Panthers are rolling after gaining vengeance on Freeland last week. They've also beaten Swan Valley in two straight, but by a combined three points. The TVC Central race has whittled down quickly, with these two and Hemlock the only three off to 2-0 starts in the league. That number will be down to at least two by the end of tonight. 

Others that caught my eye: Haslett (1-2) at DeWitt (2-1), Charlotte (2-1) at Jackson Lumen Christi (3-0), St. Johns (3-0) at Owosso (2-1), Lansing Everett (3-0) at Holt (2-1). 

Greater Detroit

Birmingham Brother Rice (2-1) at Warren DeLaSalle (2-1), Saturday

Raise your hand if you realized DeLaSalle has won three of its last four against the Warriors. Or that the teams' last eight meetings have been decided by 11 or fewer points. The reason that might surprise is Brother Rice's four trips and two wins in MHSAA Finals over the last decade -- DeLaSalle also has played in two Finals, but is seeking its first title. The winner this weekend will have the upper hand in the Detroit Catholic League Central, a great sign for another MHSAA run. 

Others that caught my eye: Oxford (2-1) at Farmington (3-0), Oak Park (3-0) at Southfield (2-1), Detroit Country Day (2-1) at Dearborn Divine Child (2-1), Monroe St. Mary Catholic (3-0) at Carleton Airport (3-0).

Upper Peninsula

Ishpeming (3-0) at Ishpeming Westwood (2-1)

This rivalry has been one-sided lately, with Ishpeming winning the last 15 meetings including twice in the playoffs. The Hematites ended Westwood's 2011 season and own a couple of impressive wins already this fall over Iron Mountain and Calumet. But the Patriots haven't given up a point since their Week 1 loss to Stephenson -- and appear due to tilt this series the other way. 

Others that caught my eye: Engadine (2-0) at Cedarville (3-0), Negaunee (3-0) at Iron Mountain (2-1), Gladstone (2-1) at Menominee (3-0), Iron Mountain North Dickinson (3-0) at Stephenson (2-1).

Lower Up North

Traverse City St. Francis (2-1) at Grayling (3-0)

St. Francis is the big opponent on many teams' calendars. That goes with winning six MHSAA championships. But both of these teams were ranked in the opening Associated Press polls this week. The Gladiators have won two straight since being shut out on opening night by Kingsley; Grayling is off to its third straight 3-0 start and looks like the favorite in the Lake Michigan Conference after watching last season's title fall out of grasp with a one-point loss to St. Francis in the regular-season finale. 

Others that caught my eye: Muskegon Catholic Central (1-2) at McBain (2-1), Petoskey (2-1) at Traverse City Central (2-1), Maple City Glen Lake (3-0) at Benzie Central (1-2), Boyne City (3-0) at Harbor Springs (2-1).

Southwest and Border

Portage Central (3-0) at Stevensville Lakeshore (3-0)

Four of the seven teams in the Southwestern Michigan Athletic Conference West appear capable of winning it, with these two joining St. Joseph among the 3-0 teams so far this season. Lakeshore perhaps has been the most impressive after finishing second in the league to Mattawan last season. But Portage Central already has equaled last season's win total and has won five straight going back to 2011's Week 8. 

Others that caught my eye: Paw Paw (3-0) at Allegan (1-2), Plainwell (2-1) at Otsego (3-0), St. Joseph (3-0) at Portage Northern (2-1), Kalamazoo Loy Norrix (2-1) at Sturgis (1-2).
