There was never anything officially said from the two but I remember a lot of rumors coming out that year that the two just didnt get along. They were professional with each other but didnt like each other. Shanny leaving for the same money was a pretty good indication of how he felt.
Didn't Shanahan have to play on a line with Draper and Datsyuk in the playoffs that year? Classic Babcock, putting a 4th line plug on a higher line.
What has Bylsma proven? He got a cup in 09 for taking over a team in February that got hot at the right time. After that he has proven to be able to take a loaded roster and get ousted in the first and 2nd rounds of the playoffs. Lets not forgot Babs was far from a proven coach when hired and that worked out well.
And hell, he barely got that Cup. If Detroit was slightly more healthy that year, we would've smoked the Penguins. They were lucky, we weren't.
