Are you claiming that no team would've traded an OL for a 4th and a 5th? Are you actually claiming that? You can say they don't grow on trees all you want, but we sent a 4th and 5th for a WR we don't need.
Are you actually going to claim no team in the NFL would've taken the 4th and 5th for an OL?
Are you claiming that Shaheed helps us more than an OL would have?
If you aren't willing to make both of those claims then you're admitting I'm right. Either make both of those claims outright or admit I was right. There is no middle ground.
Yes, I do believe that, outside of Trevor Penning, there were no offensive linemen that any team was willing to trade for a 4th and a 5th. How do I know this? Because there were other teams competing for a playoff spot who were desperate, even more than the Seahawks, for an offensive lineman.
The Chargers offensive line was devastated by injuries, and yet the best they could do was to get Trevor Penning, a player that the Seahawks would not have wanted because he would not have been an improvement and he had significant downsides. The Texans also need help on the O-line. In addition, the Commanders, the Vikings, the Packers and the Lions all are in a similar situation to the Seahawks.
I believe that John Schneider is well aware of the issues on the offensive line, and if the situation could be improved through a trade, he would have done it. I speculate that he would have been willing to part with better than a 4th round pick for a starting level offensive lineman if one could have been had. (Like he did when he traded a second and a third for Duane Brown a few years ago.)
Btw, I'm not trying to pick a fight with you. I think we all agree that upgrading the offensive line was a trade deadline priority. I think our disagreement is over whether or not there was a trade there that Schneider turned down in favor of Shaheed. (I don't think there was, except for Penning--I believe that Mickey Loomis offered Penning to Schneider and he turned it down.) I can't prove it, but all the evidence points to the unlikelihood that there was anyone available.
