There's been Ryan Johansen, and thats about it in relevant history. Johansen is not a #1A centerman, he has the talent but from what JR wrote, the Blues just didn't like him. Now I understand that even though im a RyJo fan, but he does come off as an arrogant and lazy player. We speculated it was for Shattenkirk but there were rumblings it could have been something like Parayko+(more inline with Jones). Obviously Shattenkirk for RyJo even at 8m would be a win but I would not have swapped Parayko for him. Armstrong was all over Drouin who can potentially be a centerman. Your selling him short if you dont think that he's trying to fill the hole.
It sounds like they are going to push Fabbri to center, because imo it didn't sound like he was begging for it. They brought in Schenn to play center...now I dont think Schenn is going to work but if it doesn't he filled the 2RW hole.
In my opinion this is similar to the getting fast issue. Armstrong flat out said you cant just trade for them or sign them. They are a premium and you have to draft that skillset. The Armys then went on to draft Fabbri, Barbashev, Walman, Dunn, Thomas, Kostin, and Toropchenko(those guys are just on the top of my head). This isnt EA sports where you can force a trade, you can desire and try to get a player all you want but if they dont want to come to Stl or they aren't available, there's nothing you can do.
Now with all that said, if Tavares is a legitimate option and he's not wearing a Bluenote, then I'll go get my pitchfork. As of now though, he's done a good job outside of getting value for Oshie.
