In Part 1 of the two-part free agency epic, Conor and Gary run through which will be the biggest (or, at least most interesting) teams when free agency opens.

The Dolphins are the team with the most effective cap space, the most drastic change at head coach and the most glaring holes on the roster. The Bengals’ window is wide-open and, suddenly, they’re a draw coming off a run to the Super Bowl. The Steelers have cap room for the first time in a long time, but that won’t necessarily answer their questions at quarterback. And the Colts have cap room and seemingly little desire to run it back with Carson Wentz, but that doesn’t solve their question mark under center.

Plus, the Jets continue their rebuild, and who are the teams that might create cap room to make a splash this offseason?
