well, in the smaller classes, there may be a few close games - the 6 vs 3 and 5 vs 4 matchups - but it's hard to say there will be any "good" games.
a lot of the top-rated teams either have byes in the 1st round, or they're playing a #8 seed that went 0-8 or 1-7. most of the 8 vs 1 or 7 vs 2 games will be lopsided. a couple of the 6 vs 3 games might be competitive. and then you have the 5 vs 4 games where you have a lot of records like 4-4 and 5-3 facing each other.
sad to say, but in most sections, the first round is just something you have to get through in order to set up better matchups in the semis. if you're a higher seeded team, you want to rack up a big lead and pull the starters to make sure nobody gets hurt.
I have traditionally been on the side of "let everyone in the playoffs," but in recent years, the gap between the good teams and the bad teams has gotten wider to the point where I don't think anything is accomplished by having a 7 seed get beat up by the 2 seed.
I'm at the point now where I say no more than 6 teams advance in any section. if the 7 and 8 seeds want to play each other, great. I'd rather see that then some 63-0 rout.
