I'm going to go against the grain here and say, if we can get Karlsson to come here, it should be to play on his offside, on a top pair with Weber, and to play the minutes he will be paid to play. I don't want him playing on a second pair, I don't want Gardiner if we get Karlsson to then have to trade Petry, who is a better version of Gardiner while not costing us the same kind of cap and term Gardiner would. Karlsson, for me, is the main target, Gardiner is the consolation prize, but I honestly doubt he wants anything to do with another fishbowl market that will start social media raging every time he turns it over.
A top 3 of Karlsson, Weber, and Petry is the stuff dreams are made of, handedness be damned, if anyone can handle playing his offside along side of Weber, it would be an elite defender like Karlsson. I've said it earlier in the offseason and i'll say it again, Karlsson should be target #1 on the UFA market, it doesn't mean we are going to get him, but anything else should be plan B.
