"We talk about it a bit," Martin told AFL.com.au.
"We don't know what's happening. We ask each other who you're speaking with, and what's going on, but we have to sit back from now on and let it unfold."
Martin is considered the leading candidate to be the first picked in the mini-draft, where clubs can trade with the Giants for the two selections.
One of Hogan, a key forward, and Kelly, a classy midfielder, is likely to fill the second spot, with clubs split on which player should be ranked higher.
Others eligible for the mini-draft include Matt Crouch, who has tested at this week's NAB AFL Draft Combine, and Luke Dunstan, but they appear unlikely to be at an AFL club this year.
Martin's place at the top of the group seems most clear. The West Australian is a quick, skillful midfielder, who jumps high, takes marks, and tackles well.
"He's the obvious one, everyone knows that," says Kelly, a Vic Metro representative.
"I remember the first time I played against Jack, it was probably in an under-15s carnival. I wasn't much of a player, I was sitting in the forward pocket, and he was playing at centre-half forward.
"I think he racked up 41 or something of the 44 votes in the carnival. You could tell he was a rare talent. You couldn't play anyone on him. He was unstoppable."
The race for Martin appears to be led by the Western Bulldogs, who hold picks five and six at this year's NAB AFL Draft. He has also met with Gold Coast, Melbourne and Geelong this week, all clubs with high selections or compensation picks to offer the Giants.
Martin moved from Broome to Geraldton when he was 13 in a bid to further his footy, so the prospect of going interstate next year wouldn't bother him.
"The clubs have asked about that a lot. I'm a pretty dedicated person and want to be the best and want to stick at my footy," he said.
"I'm not really that much of a person who gets homesick so if I come over to Melbourne I'll be used to being away from my family."
Already a member of the AIS-AFL Academy squad, where he got to know Hogan and Kelly better, Martin shone at this year's NAB AFL Under-18 Championships as a bottom-age player. He was named in the under-18 All Australian team.
"I was quite surprised with my performance at the championships. In the first game I went out there and I didn’t expect it to be that quick. The game was so fast and the ball was just zipping around," he said.
"I had to adapt really quickly to the game and that was a bit of a wake-up call. I went in at quarter time and told myself to adjust to it very quickly if I was to get into the game.
"I got my head around it and ended up playing a few good games after that."
