Walker's 11 year career had him playing a smattering of games per season with the St. Louis Blues up until last season when he joined the Chicago Blackhawks. In 65 games with the playoff bound 'Hawks he had 14 points and was plus seven. That seems to be the big noteworthy thing about him - he is relatively stable in that area and not a sieve. He's a lower pair defenseman though.
How does this signing effect the Lightning depth chart on the blue line? Who stays and who is AHL bound?
