Salming obviously had a huge influence on Lidstrom as he was growing up watching him - but he does give McCrimmon a lot of credit in pretty much every interview when asked who his influences were.  I have a feeling it played a big part in McCrimmon being hired, and for keeping his job.  McCrimmon really was a premier defensive defenseman and tends to get underrated. 
By the time Murphy came along, I think Lidstrom was already better than him.
