Looking ahead to the clash with Mayo the Dublin boss says that the Connacht men have improved significantly via the qualifier route.
"From what I've seen of them, I'm not surprised (they have reached final) when you look at the players they have.
"It's a very mature team and they have learned a lot. They have been in finals before so they know how to get here.
"Over the last number of games in the qualifier series, it has benefited them.
"They've got a run now and tightened things up defensively. They have introduced a few younger players from their 21 squad so it doesn't surprise me," said Jim.
