Jamar's comments came as debate rages about the potential impact of the AFL Match Review Panel's decision to charge North Melbourne's Lindsay Thomas for rough conduct after he slid into Swan Gary Rohan in Sunday's game when contesting the ball.
Rohan broke his ankle in the incident, but Thomas will contest the charge at Tuesday night's AFL Tribunal.
While Jamar refused to comment specifically on the incident, he said diving head-first was a logical approach for players when trying to win a loose ball in dispute.
"With the way the rules are now, you are probably better off going in head-first because your opposing player will actually probably hold off a bit not wanting to give away a free or get suspended," he said.
"It is probably safer now than it ever has been."
While there are risks whichever way players attack the ball on the ground, Jamar said he was already taking a head-first approach in games.
"A few guys have probably come off second best, but I did it once on the weekend and worked out all right," he said.
He said the main issue from a player's perspective was whether or not the player was making the ball his main objective.
Jamar saw first hand the effects of landing head-first when his teammate Mitch Clark crashed to the ground after a marking contest on Sunday and knocked himself out.
He said the moment wasn't pleasant, as he feared for Clark's wellbeing as soon as he saw the incident replayed on the scoreboard.
"I just thought 'I hope he is OK'," Jamar said, adding he was relieved when he saw the big man get up and run off the ground.
"I knew they weren't going to let him stay on, but it's a real credit to him the way he got up."
Jamar said Clark had been at the club both days since the incident, and seemed OK. A decision will be made later in the week as to whether the key forward will be available to play against St Kilda on the weekend.
While most observers are looking at Melbourne's draw with dread, Jamar said the players remain optimistic about the team's prospects.
"Sooner or later it is going to turn. We just need to keep attacking it the way we are, training the way we are training, and it's going to come," he said.
Meanwhile, Jamar restated his desire to re-sign with Melbourne, but added his contract negotiations had not progressed far because of the events surrounding the club through late March and early April.
"(The club) has had a lot go on off-field in the last four to six weeks, so [we are] still working through that, but it's probably not a priority for the club at the moment with everything they have been going through," Jamar said.
"I am sure in due time something will come out of it and we will be able to get on with it.
"I have always said I want to stay at Melbourne. (I've) said that publicly many times, so when the club's ready, the club's ready. That is fine."
