His original point was that we could have kept Farabee up, played Grant at 4C and we're a better team. They might not be fighting for the same spot but if you're assuming Grant is in the lineup, you're talking about Thompson or Farabee, which I think is a pretty easy decision.
A better team against which opponent?
To me, this wasn't Fletcher making moves to be seen to be busy, but responding to what his HC wanted to set up his team for a stretch run and the playoffs.
When refs start swallowing their whistles, a player like Farabee is at a disadvantage against certain teams that play a physically, chippy game - because no amount of experience will make him stronger the next month or two. Grant gives AV an option against those teams.
Thompson is a matter of a HC not trusting a rookie who's probably not NHL ready in Bunnaman.
I like the way Bunnaman has played, but he's also ultra-conservative (reflected in his lack of scoring, 2 points in 21 games) because he seems to be afraid of making a mistake. Thompson is an experienced veteran who is fine at the 4C as long as you don't ask too much from him.
Both players are UFAs, so they don't block anyone next year, and the cost was a 2020 4th and 2021 5th.
Pretty cheap for playoff insurance.
St Louis played 19 year old Thomas on their 3rd line in the playoffs, but Thomas also had 15-20 lbs on Farabee. They also brought in Maroon, and had Bozak, Steen, Blias, Sanford, Barbasheev to fill out the bottom six. Fabbri was their 14th forward in the playoffs and he played 10 games.
