That plummeting Iona line vs Buffalo

I did a little research when the line was Iona-9. Iona had played a tougher schedule, yet still had shot better in all categories and defended better in all categories. Plus Iona's game was before Buffalo's yesterday, so Iona would have had the chance to watch the Buffalo game and get a feel for their opponent. Most importantly, I read that Iona has a new coach and emphasizes full-court pressure creating turnovers. A quick look at the data showed that Buffalo turned the ball over a lot. Seems like a really good bet. Then I did the last thing I do - checked the sites with picks. They all said things like 'computer model has Iona winning by 4, so Buffalo + 9 is the pick'. Some cited last years stats for each team, which is usually not very relevant and is HUGELY IRRELEVANT when talking about Iona. Rick Pitino was the coach last year. He left and took most of the best players with him. These game-picking sites and writers mostly seem clueless dolts churning out content. But by the time I did all that the line had dropped to 6! So I then looked to see if there were injuries driving the line change. Nope. Six minutes before tipoff the Iona twitter account posted the starting lineup - same as previous games. But the big line drop made me hesitant - did I miss something? Or do lots of people bet on these trite, superficial analyses? So I took Iona on the ML at -298 instead of the spread. At halftime I see Iona is up over 20 and Buffalo has 13 turnovers. 13 turnovers in just the first half! I'd love to see data on line changes. My expectation is that most often following line changes results in a loss, or there wouldn't be any money in being a casino/sportsbook/bookie.
