Maybe Jim Boeheim was onto something. Remember when the Syracuse coach stirred controversy — in North Carolina, anyway — this week when he suggested there was no value in the ACC holding its men’s basketball tournament in Greensboro when it can be in a big city such as New York?

Well, the conference’s first-ever tournament in Brooklyn seems to be a hit, at least based on ticket demand on the secondary market.

According to TicketIQ.com, which aggregates resale market sites, Friday night’s semifinals at Barclays Center are the most expensive the site ever has recorded, by far.

The average asking price as of Friday morning for the session — which features Duke against North Carolina and Notre Dame against Florida State — was $519 per ticket, up 46 percent just since Wednesday. The least expensive had an asking price of $194, up more than double from $88 on Wednesday.

The $519 average price for Friday night is roughly double what semifinal tickets have gone for over the past five tournaments, three of them in Greensboro and one each in Atlanta and Washington - two other big cities that Boeheim endorsed as ACC sites over Greensboro.
