Central Division predictions

Got another 3 out of 4 correct this past week, giving me only one game wrong in the Division to date. Of course, we'll just ignore the fact that the game I lost involved my predicted champion (Colton). Sounds good to me.

Rancho Cucamonga at Los Osos
This one is, as Bostonians say, wicked hard. Who do you pick against, the hottest team in the division or the division's defending champion? Los Osos' six-game winning streak started against the Cougars, as the Grizzlies took them down 31-28 in Week 7. However, Rancho Cucamonga took out a Colton team on a 10-game winning streak last week and are a little peeved about the Grizzlies wearing their home uniforms at what was supposed to be a Rancho home game? So where do I go from here? I'll take the hot team, though I have no real confidence in this pick.

Upland at Chino Hills
Once again, Chino Hills had my back and then some, beating Etiwanda down to move to the semifinals. They'll try to take out another Baseline team again, as they go against an Upland team that knocked off No. 2 seeded Colony in a tight one to make it to this point. Both of these teams have great defense and both of them are battle-tested, but you have to be on some drugs if you think I'm getting off the Chino Hills bandwagon now. I'm riding shotgun until the journey ends.
