ok, so if it's points or points per game then you have to look at the context and realize how advantageous his usage is - Gardiner would have been about a 64pt/82game player with Barrie's PP time assuming he maintained the same (very maintainable) production per pp minute
age - it's a year, they're both in their late 20's...it's a difference I guess, but marginal
contract - with the Ryan Ellis signing, I don't think Gardiner gets more than Barrie and if so it's going to be within $500k/year and probably half of that. Gardiner currently makes almost $1.5M less than Barrie, so the break even on Gardiner costing more than Barrie is 3-6 years into the future...this actually could count against Barrie in real dollars for comparison's sake, but so so negligible a difference
talent - that's completely subjective, Gardiner is an extremely talented player, former mid 1st rounder and coming off his own 50pt season
so I think this comes back to looking at hockeydb, seeing how many points in how many games, and assuming that's an apples to apples comparison where it's far from that
see above
