So a offering a high round pick and making Albert one of the highest paid players on the team is just the GM doing his due diligence and leaving no stone unturned? Your theory wasn't good when the rumor of the trade first came out, most probably believed Philbin wanted the upgrade at that time. Then it came out that Martin skipped out on training camp and attempted to kill himself and your theory looked silly at that point. Then it came out that multiple sources said Philbin was the one that wanted the Albert trade and your theory should be flying around the room like a popped balloon. And now Brandon Albert actually is a Miami Dolphin, we couldn't wait to sign him, literally couldn't wait to sign him and your theory at this point...well, I won't say what I think of your theory at this point cause it'll likely get me an infraction.
As far as whether Joe Philbin deserves some blame for Martin being on the team I don't know how much blame he deserves for that. Nobody does because nobody has any idea on the inner working relationship between the two. Philbin reportedly wanted Incognito cut after the sexual harassment and Ireland said no to that so that would suggest Philbin didn't have much say in anything personnel related. That is not the point though, the point is Philbin tried to correct the problem before it was too late, and it doesn't matter who was to blame for the problem, we still had the time and resources to fix it...during the offseason. Philbin had the foresight to see the problem coming and he tried to fix it at the appropriate time, Ireland's biggest problem is he had no foresight, he could only fix things he could see in the rear view mirror. In this instance even a mediocre GM probably gets us at least another option at LT, which probably gets us into the playoffs, which takes the heat off our Head Coach.
Philbin should not be making personnel decisions imo, whether Albert turns out to be good or terrible Hickey still deserves most of the credit/blame for that signing. Hickey can use Philbin as a resource to help him make his decisions but he should not be letting his resource make the decisions.
