I think you need 3 components, not 2 ...
(1) skill
(2) luck
(3) the human element
For teams with approximately equal skill, the human element, not
luck, will often be the key secondary factor.
I'll outline two categories of situations for which the human
element may be the key factor ...
(1) Strategic Adjustment
Team A's chosen strategy may take team B by surprise, but
by the second half, the surprise has worn off and team B has
made appropriate adjustments.
Or, for multi-player team games, perhaps some player on team B
is not playing well in the first half, so that player is
replaced in the second half, and then all is well for team B.
(2) The Emotion Factor
Suppose Team A wins the first half by a large margin. In the
second half, it's hard for team A to psyche themselves up for
maximum output. Thus, team A will tend to "coast", riding their
huge lead. At the same time, provided team A's lead is not too
much to overcome, team B may be psyched to play at absolute
maximum skill and power, thus potentially recovering some or
all of the initial score deficit.
On the other hand, suppose team A gets a huge, essentially
unrecoverable lead in the first half. Then, in the second
half, team B may have lost the heart to fight, so gets crushed
even more.
Alternatively, for the huge, unrecoverable lead scenario, the
coach may make some substitutions to try some untested players.
It's a good time to experiment since the game is lost anyway.
Thus, with team B using their "B team", the second half may be
even worse.
Bottom line -- I think the human element dominates the luck
element, and would be hard, perhaps impossible, to filter out.
