Not even close. Quantity doesn't equal quality. You want Columbus to trade its Franchise defenseman who's a top 5 in the league D in his prime AND Korpisalo for a UFA goalie, an AHL plug, a B level prospect defenseman, a 5/6 defenseman and a late first round pick?
Robertson is the only good part of this trade for Columbus. Jarmo would lose his job if he made this trade.
