Barby has a 60 point season under his belt with us. He has back to back 45 point seasons with Vegas and that production was almost exclusively at even strength. He has 28 points in 28 games this year and has consistently been in the top 6 during his time in Vegas. He is 98th in total points among NHl forwards since the start of the 2021/22 season and is 51st in even strength scoring over that stretch,
Barby isn't a driver and is benefitting from playing with good line mates, but he is a legit 2nd line talent. I'm guessing you meant the type of guy Barby was through most of his tenure as a Blue, but I love Barby and will pump his tires every chance I get.
As for Holloway, I see more 'our new Schwartz' than Perron if we're trying to draw a comparison to our Cup team. Great motor, great instincts, streaky production, and prone to a lot moments where the hands/skills can't execute what he wants to do with the puck.
