After what happened last year, you’d think it would be too hard for Marty Walsh to watch the Summer Olympics.

Actually, the mayor catches as much as he can on a 52-inch-screen TV at his Dorchester home. He spent several hours over the weekend watching women’s soccer, men’s basketball, and all kinds of swimming.

“I love watching the Olympics,’’ Walsh said.

Of course, he would have been in Rio had Boston’s bid for the 2024 Summer Games not collapsed last July. Representatives of potential host cities typically attend the competition to woo members of the International Olympic Committee.

Instead of Walsh, LA Mayor Eric Garcetti is in Brazil.

“It’s fine,’’ Walsh said of losing the bid. While he is rooting for LA, it will be tough if an American city gets the nod. “I will think about what could have been,’’ he said.

Steve Pagliuca, the former chairman of Boston 2024, is not only watching the Olympics, but he will be down in Rio next week to make the case for LA.

Pagliuca, a Bain Capital honcho who is also co-owner of the Celtics, in June joined the board of Los Angeles 2024, the group that is trying to bring the Summer Games to LA.

In addition to basketball, Pagliuca likes to watch tennis and beach volleyball. While in Rio, he plans to meet up with the US Olympic Committee and the LA 2024 team.

“They have a great plan in LA and great support from population and government,’’ Pagliuca wrote in an e-mail. “I think we have real shot for LA to win it in 2024. Fingers crossed.’’

As for former Boston 2024 CEO Rich Davey, he isn’t watching much Olympic coverage.

“Funny, I haven’t been able to,’’ Davey wrote in an e-mail. “I have DirecTV in Boston, and they seem to be in a fight with NBC!’’
