I agree taking the 2 was the right choice.
They were maybe a 20% chance of scoring a try based on their tackles in opposition 20 to try ratio, or 100% chance of kicking the penalty. Guaranteed 2 wins that bet every time a few seconds from halftime.
They are now a single try from taking the lead instead of needing to score twice to win, and on top of which if you could have offered the eels a halftime deficit of 4 points 20 mins into this match they'd take it without hesitation.
Good fight back from the eels. Still expect the cowboys to win although a good team would have put the eels to the sword by now
