I understand that AMac's rehab is supposed to last until the and of the month. Nonetheless, this article in Newsday is a reminder of how precarious the Isles' situation on defense really is. Any projection of Islander success this season relies heavily on AMac playing a key role on one of the Isles' top two defense pairings. It is hard to imagine the impact of any hitch or delay in AMac's rehab on the team.
This is why Garth Snow's failure to add a top-4 defenseman coupled with his decision to let HIllen and Martinek walk is tantamount to malpractice -- even if AMac starts the season healthy. He is just leaving the teams's defense at undue risk.
The team has ridiculous excess of talent at the Forward position, and to a lesser extent, in goal. There will be no room for all of these pieces down the line and trades of young prospects will be a necessary part of obtaining the final pieces to the puzzle. Why not do that now? If the answer is that Garth tried and was unsuccessful, that tells me that there was no good reason to let Jack and Marty walk.
