Mario Williams' visit was with the Miami Dolphins was a long one.
How fruitful it was remains to be seen.
Williams spent Saturday night and most of Sunday huddled with team brass in the Dolphins' Davie headquarters, where Mike Tannenbaum and company presumably made their best pitch.
Williams is among the top available defensive ends in free agency this year, and made Miami his first stop after the Bills cut him last week.
Williams, the former No. 1 overall pick and four-time Pro Bowler, told ESPN that he plans to meet with "four to five [teams] quickly " before making his decision.
It's unclear if the Dolphins could have convinced him to cancel those meetings by outbidding the market. Williams is 31 and coming off the worst season of his career, so the Dolphins might see him as a cheaper option than Olivier Vernon, whom they gave the transition tag last week.
If Williams agrees to a deal with the Dolphins, it's likely that Vernon will go elsewhere, but not guaranteed. The Dolphins would have the right to match any offer he receives in free agency.
Meanwhile, the NFL's legal tampering window opens Monday. All 32 teams will be allowed to speak with the agents for players set to become free agents on Wednesday, which is the first day a contract can be signed.
