?? You’re defence is old, kylington will break out offensively if given ice time and is young. Same with Dube.
So you legitimately think that is a decent offer? My word.
Myers, OEL and Schenn are older than 30, which seems to be the magic cut off for players considered "young". Burroughs, Hughes, Bear, Stillman, Rathbone, Dermott and even Poolman are under 30, most much closer to 25. Kylington is 2 years younger than Horvat, and Dube is 3. Age isn't every thing, and we're not getting much younger on either count.
Both are absolutely redundant in terms of skill set and position. They aren't getting that ice time. That list above has 6 players that play the left side, with two that would undoubtedly get the prime offensive time you're saying Kylington needs to "break out", and one more we're already struggling to get enough ice time for.
Dube would be fighting it out with 10 other wingers, not counting Miller who would presumably be playing center with Horvat gone, for a spot on the team. He is not getting ahead of 7 of them to get into a top six role to get that ice time either.
Both of them combined doesn't get you a 30 goal scoring center currently second to only McDavid in scoring. It's an insulting offer, frankly.
