BOSTON — Suppose your teacher told you that an assignment was due by a certain day. You stayed up half the night, produced a nice-looking package a day before the deadline and patted yourself on the back for handing it in early.

But when the teacher looked at it, much of the assignment had not been completed.

That was the anticlimactic feeling here Monday, when Boston 2024, the private group organizing the city’s bid to host the 2024 Summer Olympics, put out a much-anticipated report that Gov. Charlie Baker of Massachusetts had asked for by Tuesday.

Boston 2024 held a briefing for boosters and the news media Monday morning at the Boston Convention and Exhibition Center. It gave out gorgeously produced briefing materials, and officials later briefed the governor.

Their main pitch: The overhauled plan, updated from a widely panned version first offered in January, would generate millions of dollars in new tax revenue, create tens of thousands of new jobs and produce thousands of new housing units, parks and other neighborhood amenities that would provide a lasting legacy.
