Betting on Football First Half Lines
How many times has the team you wagered on staked out a decent lead, only
to let it slip away in the second half? Fans of the Bears (led 20-0 but lost
29-23) and Titans (led 21-7 but lost 31-28) and to a lesser extent the
Vikings, Seahawks and Chiefs understood your pain this weekend. If you have
never tried betting on First Half lines you are missing a valuable tool from
your wagering arsenal. That is the topic for this week’s column. I will
focus on the NFL for today but please note that most of what you read today
will be directly applicable to college football as well.
Books offer first half wagering for the simple purpose of increasing
handle. The more you bet, the more (hopefully) the book earns. There is not
much secret in how First Half lines are derived - generally it just the
pointspread for the game cut in half with a half-point to full-point
adjustment against the favorite. For example, the Sunday Night Falcons-Bengals
game had a pointspread of –7.5 and a First Half spread of –4 or –4.5. There
is usually a bias against the favorite team because bettors tend to prefer
them in the First Half as perception is that the favored team is more likely
to get out to a quick lead in the First Half before allowing a “back-door”
cover in the Second Half. However, I have yet to see any statistics that
prove that either the dog or favorite for the game are a better bet. Like
any other bet type, you need to pick your spots.
It is very easy to find a team’s total points for and against for the
season as a total. Every newspaper and major sports website provides this
readily. What is tougher to find is a team’s points for and against by Half.
I track this myself every week in a spreadsheet and it helps as interesting
mismatches do appear. For example, one of the comparisons I make is a team’s
scoring margin in the First Half compared to a team’s scoring margin in the
Second Half. After 2 weeks, Miami was the best First Half team with an
impressive 49-10 scoring margin in the First Half. Compare this with their
21-24 Second Half numbers and I think you can quickly see where the
opportunity lies. Other top First Half teams for the first two weeks were
the Chargers (37-3 in the First Half) and the Eagles (47-17) and playing all
three of these teams for the First Half this week would have made you 3-0.
The worst three teams after week 2 were the Bengals (0-37), Lions (7-38) and
Rams (13-33). Betting against these three teams in the First Half this past
weekend would have made you 2-1 (the Lions covered by being tied 21-21 with
the Packers at the break). This is by no means a system, just a simple
analysis that happened to work on one NFL weekend, but it is definitely
something you can easily do in a few minutes every week. If 15 minutes a
week of tracking scores by half leads you to find a single winning play,
then it is worth it every time.
Another stat I track is a comparison if a team’s First Half performance
relative to it’s Second Half performance. I feel that the spread is a good
indicator of a team’s overall performance for a game but that the
bookmaker’s system of cutting the spread in half cannot be an efficient
indicator of First Half performance. Looking at the Dolphins again, they are
–3 in the Second Half and +39 in the First Half. Therefore I rate them a +42
for First Half over Second Half. Other top teams on this list (for the first
two weeks) are Cleveland at +34 (+23 and –11), Philadelphia +33 (+30 and
–3), Minnesota +30 (+10 and –20) and the Falcons at +26 (+11 and –15).
Betting on these five in the First Half for week 3 would have made you 4-1.
The worst teams on this list (which might make good teams to play in the
Second Half) are the Bengals –33 (-37 and –4), Bears –31 (-18 and +13), Rams
–28 (-20 and +8), Patriots –27 (+13 and +40), and Packers –26 (-19 and +7).
Betting against these five would have also made you 4-1. Again, not a system
by any means, but something that bears watching to make you a more
profitable bettor.
In summary, it is worth your time to track all teams’ performance by Half
and look for inconsistencies in the First Half line. This past Sunday night,
the Falcons were 4-point favorites in the First Half. Considering Atlanta
had outscored their first two opponents 21-13 (in Green Bay) and 10-7 (at
home against the Bears) in the First Half before losing both games outright
while the Bengals had yet to score a First Half point (but had given up 37),
that line looks very low. The Falcons led at the break 20-3 and if you had
the First Half bet, you could now get some sleep and not worry about losing
your bet (or even worse, watching the Bengals play another 30 minutes). Take
this with a grain of salt though as it is very easy to pick winners the day
after the games are played.
Once again, I am pleased to offer Kent’s “Move of the Week”. Kent is
BoDog’s top bookmaker and He has graciously agreed to provide us with
detailed insight into one game every week. Here are his thoughts from this
past weekend:
“The Move of the Week comes to us from NFL Week Three
where it was a mixed bag of results for the House. One result that favored
the House was the public continuing to play on a Minnesota Vikings team that
looks long removed from the form that saw them make the playoffs a few years
back. The line came out at solid Vikings -6 and stayed that way throughout
the week before creeping up to -6.5 late Saturday and then moving up to -6.5
(-115) before finding it's final resting spot at Minnesota -7. I also
started at -6 and let the public drive the line up to -7 where we would hang
tough and let the folks fire away. In case anyone missed it, Minnesota is
now 0-3 while the Panthers are 3-0. Now make no mistake, the Panthers are
not that good however the Vikings just may be that bad. Minnesota had a heck
of a time stopping Bledsoe and the Bills receiving trio of Moulds-Reed-Price
last week and this week made RB Lamar Smith - cut by Miami - look like
Marcus Allen as he rushed for 154 yards. Looking at the Vikings as a
football fan, they seem to be trying to put Moss into every play and the
result is that Culpepper was intercepted 3 times while trying to throw to
Moss. The Minnesota QB also managed to fumble once. It doesn't get any
easier this week for the bettors to figure out the Vikings as Minnesota
travels to Seattle where the Seahawks have been pegged as a 3-point favorite
at home. In a match-up of two winless teams the home team has been made
given the Field Goal which is directly attributable to them having the
home-field edge - on a neutral field this game would be a Pick. It will be
interesting to see how the bettors respond to this match-up but as of right
now the number looks right.”
Thanks Kent. I will be back next week with a column on Halftime betting.
Thanks for reading and good luck.
