just my opinion:
1) his totals might be different than the majority of the totals you see. obviously i have no clue how he adjusts numbers, but for example- you could see a total at an online book of 8.5 over (-130) where as he might use a total of 9 at (-110). the half run obviously makes a difference
2) sure there might be "value" in betting the heavier-chalked side at -110, but (and im not trying to sound like a jerk at all), you cant just blindly play something you dont like just because "you get a good price on it".
by that i mean say his total is 9.5 under (-110) whereas the other lines you see on the internet are 9.5 under (-125) or (-135).
yes, some might say theres "value" there, but if you just blindly play it without liking it (which some people have a tendency to do), then it just becomes "a pile of sh1t wrapped up with a bowtie around it"- meaning its a loser, no matter how you slice it- even if you saved a couple of bucks.
my suggestion is to keep an eye out for totals you like and the (-110) juice will help you over time.
but dont fall into the habit of "playing something just because you get a good price on it"
you have to like a play- not a price, per se
