Eye test!
Rozsival occasionally made some bad gafs and was another in the long line of "offensive defensemen who doesn't hit!" even though he wasn't really that big or an offensive defenseman. People remember the gafs, they don't remember when he played well.
Malik was a big guy who wasn't physical so of course he was hated from day 1. He's the kind of player that I wonder what advanced analytics would say about these days because I don't remember him being very good but could see him as one of those guys who actually turned play the other way quickly and was better defensively than people thought (I seem to remember he was good with the breakout passes).
That said I also seem to remember they basically were attached to Jagr at the hip and probably benefited hugely from playing with him all the time.
