I pose it as a question because I don't have a link to a printed source, but I've now heard this mentioned on tv twice. Once by NHLN and once by CBC. Both said that Datsyuk made a request to Babcock, with all the injuries, to keep Abdelkader on his line because Abs provides what Dats wants, and keeps it simple. If true, this sure makes a lot of those comments about Dats suffering/wanting to return to Russia/'surely upset and angry' seem quite silly.
Its also mentioned by Ken and Mickey on fsd
It's not so bad having 1 of Abs/Cleary, but both is just absurd. If the line was Z-Dats-Abs then it would have the Z-Dats-Homer effect, but with Cleary on the other Wing, it's just Mike Babcock pulling shenanigans with his lines.
