Probably need to be clear on whose drop kick can they be offside on. If you are on opposing team of the keeper making the kick, you cannot be offside. If you are on same team as keeper making the kick, you can be offside. Given that the payer in question is just starting with the offside rule, I'd suspect the most likely scenario is that they will not be offside.Can't be offside from a goal kick, but can from a keeper's drop kick.
