While there are many shiny new toys ready to be purchased, the buyer better beware before investing their money in these players. Every year, we see some teams (cough cough Dolphins cough cough) give a star free agent a ton of money, only for it to blow up in their faces as the team doesn't improve and their cap space shrinks.
Overall though, I think the Eagles did a pretty good job on day 1. I know that in today's NFL that day 1 is really stretched over the prior two weeks and today is just the day a lot of these deals just get finalized today, but the Eagles came in with a strategy and executed it well over the first fortnight of free agency.
