I'm not even really criticizing them in this case.
My point is that a team like the Rams and other bottom feeders would look at an FA like Clay and say, "we can get a top 10 TE for top 3 money, is that going to be worth it?" And they would decide, "no," because they have holes elsewhere and having all that money tied up in 1 player won't be the last push they need to make a postseason run.
Whereas a team like the Bills may be saying, "we already have a pretty good gaggle of talent with a few holes and we feel we are a playmaker or two away. What is better for us for the next 2-3 years, signing 2 middling FA's competing for jobs or overpaying for a good player?" And in their mind, overpaying for Clay is worth it.
See the difference?
