The bell has rung on the New York Stock Exchange again here on Monday, morning, but Kosmo doesn't care about that. He's ringing the bell on his own stock exchange as it relates to Oakland County football teams. There is already four weeks of the season in the books, so here are Kosmo's rising and falling stocks, er teams, after Week 4. Rising Oak Park - Well, your seer guesses he can officially say the Knights are for real. Following a 24-18 overtime win at Southfield, Oak Park is 4-0 and has a first-place battle with 4-0 Farmington at home on Friday in the game of the year so far in the OAA White. Walled Lake Northern - Another team named the Knights, Northern played its guts out and was rewarded for it with a 17-10 home win over Walled Lake Western last week to improve to 2-2. Now the other city foe, Walled Lake Central, comes to Northern's field this Friday. The Knights have never beaten the Vikings. Birmingham Detroit Country Day - If not for a bad fourth quarter in Week 2 against Detroit U-D Jesuit, Country Day would be 4-0. But still, the Yellowjackets are 3-1 and looking good. Hopefully they get some love in the Divison 4 state rankings. Pontiac Notre Dame Prep - The Fighting Irish just continue to amaze, winning a first-place game against Ann Arbor Gabriel Richard last week to improve to 4-0. Notre Dame Prep has won 17 straight regular season games. Falling Southfield - All of a sudden, the Bluejays might be in some playoff trouble. They are 2-2 following the loss to Oak Park and have to play at Farmington Hills Harrison this week. With a home game against Oxford and a road game at Rochester Adams remaining, not to mention a crossover game against an OAA Red opponent in Week 9, and Southfield has work to do. Ortonville Brandon - Kosmo thought the Blackhawks could contend for a playoff spot again after making the postseason last year, but they are off to a tough 0-4 start in the Flint Metro. Rochester Hills Lutheran Northwest - The Crusaders fell at Livonia Clarenceville and are 2-2, so they'll have to fight the rest of the season to return to the postseason. Northwest has a game against Sterling Heights Parkway Christian this week.
