In my personal opinion, from having watched Riverside personally and having heard the opinions of others more 'knowledgeable' than me, I have to concur that Riverside is pretty darn good. Probably as good as they were last year, and will be hard to beat.
McKenzie is about as good as they were last year, too, Just better in different areas and not as good in others, in which it all balances out.
I may be a McKenzie fan, but I try to be realistic, if not sometimes pessimistic (I know, not good), and I have to say I like our chances.
I'm going with McKenzie, 21-7 (last year was 22-7)
