I like CTs suggestion of 5 points for a sole predict a score winner and the usual 2pts (or 3?) if there's more than one winner. This would also double, treble etc. on the roll overs just like before.

I can see the conundrum over allowing free reign on draws due to the fact that people might just go for 10. The only way that could be curtailed (and it would complicate the scorers job immensely) would be to introduce a penalty score of e.g. -1 for every draw prediction that was incorrect. e.g. predict all 10 draws but only 3 are actual draws you would score just 2 in total (3x3=9 - 7 = 2).

I'd like to see the Joker double your entire score for the week not just your predictions score.
