Here are five general observations from Arthur Arkush about the start of a frenzied free-agent period:
1. Playing with fire in the desert
If the Cardinals get 2016 Sam Bradford, their decision to guarantee him $15 million coming off a year in which he played four quarters of football, albeit brilliant football, before his season was ultimately over won't come back to haunt them.
More likely, Bradford's chronic knee issues will creep up again and the Cardinals will turn to Mike Glennon, not a terrible QB2, per se, but very unlikely to morph into January Nick Foles and keep Arizona's ship afloat, either.
