They can't manufacture players, and the consensus is that there isn't a single good FA OT out there worthy of a major contract. The only one on the list that's worth signing is our own guy.
The WR that will be available are aging and thus probably won't be around when they have finished the rebuild and are ready to compete for championships.
Lots of "excuses."
So you build around those deficits. They can get good solid OL in the middle of the free agent group, re sign defenders and add defensive free agents, and then rebuild the offense through the draft and cap casualties. I also think that making a run at Tyron Smith for a 2 year deal could make some sense. Then draft an OT with their 2nd pick and start them out on the right side. They could move up for Guyton, who played a blindside RT at Oklahoma, and then either move him, or use a top pick next year to get their LT. But regardless of individual moves they need to understand how to maximize free agency/ spending, cap casualties, and the Draft to start building them into a yearly contender.
