Caddy said his desire to play with his childhood friend and former Gold Coast teammate and housemate Dion Prestia was a factor in his decision.
He also liked the idea of spending more time in the midfield.
“My name was thrown up and it was put to me would I possibly think about that (a move to the Tigers),” said Caddy, who signed a four-year deal.
“That was the first time I really did think about it and then that fell through, but Richmond was still really keen.
“It was a tough decision but I just weighed up a few things. I thought it was probably a great opportunity to further my career.
“Two weeks ago I was happy to stay there and keep fighting for a spot in that midfield but when an opportunity opens up that you didn’t see coming (you take it).
“You live and die by the sword and time will tell, but I believe I’ve made a good decision.”
Caddy said Prestia “was into me straight away” when he joined Richmond.
“It definitely played a part,” he said.
Geelong recruiting boss Stephen Wells said the club was disappointed to lose Caddy, who he said had requested the trade.
“I think the Tigers convinced him that he was going to get some tremendous opportunities there,” Wells said.
“We thought he had great opportunities with us as well.”
