Okay, so in this confusing table, I've marked 3 possibilities for each player: a winger, a 2C, and a 1C for Kotkaniemi, and a 3D, a 1D which should be interpreted as a good starting pairing dman, and Erik Karlsson, for Boqvist. The X indicates which player I would regret taking in the scenario indicated in each column.
Essentially, we have to pick a row. A criterion for picking a row could be that you want to pick the row with the smallest sum. If all regrets are equal, and the likelihood of each column is equal, that means Kotkaniemi loses by a factor of 2. Now, not all columns are equally likely (the EK columns are perhaps the least likely), and not all the weights are likely to be equal. For example, is it better to have a 1C instead of a 3D? Or a 3D instead of a W? To select your player, you'd have to multiply your regrets by their column likelihood, and sum them up for each row, and choose the smaller number.
An alternative is that we can select the row with has the smallest maximum regret. The maximum regret in Jesperi's row would be that he turns into a winger, while Boqvist turns into Erik Karlsson. The maximum regret in Boqvist's row would be that he turns into a 3D while Jesperi is, at last, the fabled unicorn 1C. I think Boqvist wins by that criterion.
