I'd be interested in going through the years and comparing.
2010 STA on paper one of their best teams ever. That being said, MC seemed to struggle vs option teams back then and I would be kidding myself if I said MC couldn't give STA a game.
*Playoff difficulty very slight edge MC only because South Dade>>>Cooper City. Both Miami and Creek sucked. BA beat Cypress bay 36-17 that year. Manatee and Plant vs MNW and DP would be a VERY interesting debate (back then I would have said Manatee/Plant no doubt), looking back ehhh I think it's pretty close.
STA: beat Camden County GA 42-28 (home), beat Cypress Bay 60-14 (away)
*playoff wins: Coconut Creek (59-0), Cooper City (49-7), Boyd Anderson (47-6), Manatee (31-7), Plant (30-7)
Central: Lost Camden Co GA 42-45 (away), beat Cypress Bay 30-27 (away?)
*playoff wins: Miami (55-0), MNW (42-27), South Dade (38-7), Cypress Bay (30-27), DP (42-27)
2010: Edge STA (MC was NASTY though)
I'll try and do 2011 and 2012 tomorrow.
