Pure speculation here, but it feels to me like Ireland forced Martin on Philbin at LT because of his own agenda with the money being spent and to protect his draft pick. If the coach is telling you the kid can't cut it at LT and he wants a backup plan, it seems to me coach has doubts that need addressing.
If you throw in all of the other decisions made during the draft and FA, only drafting a project in Thomas, spending so much money on Wallace, stringing out the Albert saga but doing nothing, balking at Long's contract demands, balking at McKinnie when he was a FA and a few others, then I see supporting evidence that Philbin was asking for more OLine help before the process started and Ireland shifted financial and draft resources away from it to make bigger splashes and make himself seem more aggressive.
It's not that he didn't have options and opportunities to fix this problem long before it happened, he simply wanted to ignore the problem and put the responsibility and failure on the staff when the OLine failed and made all of his moves look bad.
His short sighted approach backfired and cost him his job. Sadly, we could have acquired Albert (albeit with a high contract and a 2nd round pick) or kept Long (for a smaller contract than Albert and no draft picks) and McKinnie (for no draft picks) long before camp and we would have never had Bully Gate and our QB would spent a lot less time on the ground and possibly had a few more W's in the column.
But we didn't because a person finally allowed to spend money freely within reason decided to ignore 1 or 2 signings when neither would have truly hurt us. And we still have to address those holes and we've already spent draft picks but they didn't go to a long term solution. McKinnie for free was a nice option for a stop gap and depth. For draft picks and the same price, now we have to hope we can get 2 or 3 more years at the same level out of him.
Understand, I'm not saying go back and not sign Player X in order to acquire OL Player Y. I'm saying we had the opportunity to sign those guys IN ADDITION to the others and the holes would have been plugged and the other pieces could have gotten better, quicker. Helping the investment spent in other areas.
The problem was mentioned and it was firmly ignored. And to prove a point, he blatantly ignored it to spite his coach. Glad Ireland is finally gone.
I would like to know how many times and what players Philbin was denied by Ireland. Along with the players Ireland substituted based on his own judgement. Not so much to judge Ireland, but to see how much better/worse Philbin is so we can get a better understanding of the man and his real abilities.
But alas, that information will never truly be discovered.
