The point is that guaranteed means guaranteed. It’s true that agents and perhaps teams like to lie about the terms of a contract, this isn’t new. It’s also not new that sports reporters tend to not be the most critical thinking group and can be lazy in their fact checking. However I think it’s a touch silly to use this as justification to invent a new meaning of a word. Because Manning’s deal was reported as having $54.4 million guaranteed isn’t reason to draw the conclusion that there’s a new NFL specific meaning of the term guaranteed. Had you asked if Lynch’s deal was really worth $18M guaranteed or if it was exaggerated and included differed bonus money that would have made sense. As you wrote it it was an oxymoron. In either case you’re taking this way to personally.
If that happened I wonder if the plan would be to release/trade Schaub or retain him as a backup/contingency plan. Houston does make for a pretty compelling landing spot, perhaps better than even Miami. Not sure how Peyton would feel about going to a division rival, though I’d suspect he’d relish the thought.
