You brought up a very important point: That Jesus linked the time of the end and "this generation" with Daniel's 70 weeks prophecy.
Mathew 24:15 has as a reference Daniel 9:27. Daniel 9:27 speaks of the last week of the 70 weeks of Daniel.
The jw's say that last week of the 70's weeks already took place in the first century.
Many bible researchers say the 70's week will be in the future.
From Daniel 9:24-27 you can see that there is a gap between the 69 and 70 week. The jw's do not recognize this gap.
If you read the whole context you can see that during the last week a short term - 7 year "covenant" is made by a price of the country who comes to destroy Jerusalim, but he breaks the covenant at the half of this period of 7 years.
The wt even changed the verse Daniel 9:27 to make it appear more that the covenant is made by Jesus and support the fact that the 70th week already took place. NWT States “And he will keep the covenant in force for the many for one week; and at the half of the week, he will cause sacrifice and gift offering to cease.
While NIV : He will confirm a covenant with many for one ‘seven.’[h] In the middle of the ‘seven’[i] he will put an end to sacrifice and offering
