2A might be the most open bracket this year, no clear favorite with Wilmington bumped to 3A, and just about everybody left has a puncher's chance of winning it. QND probably the current favorite, but their matchup this week with Maroa-Forsyth should be a toss-up.
As for Chicago Christian in Palos, they're a real solid team this year, new coach, new scheme, senior-laden. Rarely make noise in the playoffs (I think this is the second time ever in the quarters for them). Took it to a really good Tri-Valley team on their turf last weekend.
