Last week produced almost 190 points per game, which was about 3.5 to 4 goals higher than our forecasters' expectations, but this hasn't much elevated expectations for this week, especially those of the bookmakers.

It seems very unlikely we'll enjoy close football this weekend of the likes we saw on Friday and Saturday of Round 20 - at least not in the quantity we saw there, with this week's fare including only one game with an expected margin of under two goals.

This week for the MoS twins was mainly about MoSSBODS' coming to agree with MoSHBODS' ranking of West Coast, and the pair coming to agree also about the ranking of Port Adelaide. West Coast are now 5th on both Systems, and Port Adelaide 10th.

The RSMP twins regained lost ground this week, but still sit three tips behind the second-placed Bookie Knows Best and four behind the leader, ENS_Linear, who is now on 122.5 from 171 (72%).

Another week, another sub-170 point average total score expectation, though this week we can maybe hope that four games will exceed that threshold.

All five of this week's Saturday games are expected by the bookmakers to be won by less than a goal, though the average for the whole round is blown out somewhat by the 44 points plus expected margins for the three Sunday games and the 21.5 point expected margin in the Friday game.

Some stability at the top of the MoS twins' ratings this week where we find exactly the same Top 4 teams at the end of the round as we had at the start. For MoSSBODS, that's Richmond, Melbourne, GWS and then Collingwood, while for MoSHBODS it's Richmond, GWS, Melbourne and then Collingwood.

The RSMP twins dropped a tip further back this weekend, leaving Bookie Knows Best now four tips clear of them, and ENS_Linear now six tips clear on 116.5 from 162 (72%).

This week, according to the two bookmakers, we should expect about 165 points per game, which is roughly one point per game below the season average.

Only two games this week have expected margins of more than 19 points, and three are in single digits, which means that the average expected margin for the round at 16.6 points per game is the lowest it's been for a single round since Round 13 and the sixth-lowest it's been all season.

Traditionally, this has been the time of year when team rankings on MoSSBODS and MoSHBODS have been` fairly stable, and the norm was for a handful of teams to bounce up or down by mostly a single spot, and occasionally a couple.

Just two underdog wins this week, and none of the Head-to-Head Tipster front-runners tipping either sees the round finish with ENS_Linear still two tips clear and now on 110.5 from 153 (72%).

We seem now to have settled into a collective view - shared by the MoS twins and bookmakers alike - that the new normal is rounds of AFL football producing average total scores somewhere around the mid 160s.

This week comprises four games where the expected margin is under two goals, and five more where it's five goals or more, which has landed the all-game average at just under 27 points per game, the third-highest average for a round in the season to date.

MoSSBODS and MoSHBODS had different opinions about what the Giants v Tigers game revealed of the relative abilities of those two teams, MoSSBODS focusing solely on the Tigers' superior scoring shot count, but MoSHBODS also looking at the final score.

Only four favourites won this week and just two of the MoS Head-to-Head Tipsters - C_Marg and Home Sweet Home - managed to tip one of the upsets.

Another weekend of relatively low scores seems to be in prospect, with only one or perhaps two games likely to see over 170 points scored, and only one or two teams likely to register three-digit scores.

Two games this weekend have an expected margin in single digits, and two more have expected margins of around two goals. The largest expected margin - for the Dees v Dogs game - is about 33 points, which leaves the majority of games in the two to four-and-a-half goal range and has produced the lowest average TAB Bookmaker margin since Round 13. It's 17.9 points per game this week.

Richmond held top spot on MoSSBODS and MoSHBODS this weekend, doing about as well as both Systems expected in their game against Adelaide.

Sydney were the only favourites to lose this week, which combined with low levels of disagreement amongst the Head-to-Head Tipsters, made for high scores. Seven of the Tipsters scored eight, and none scored lower than Home Sweet Home's six, resulting in an all-Tipster average of 7.7 from 9.
