Here are the moves the Tennessee Titans should consider when free agency opens at 4 p.m. ET Wednesday:

Priority No. 1 -- Find veteran leadership for the offensive line: If Tennessee wants to get the best lineman out there, Baltimore's versatile Kelechi Osemele would be great. If the Titans want to sign a much better right tackle than they've had the past two seasons, such as Mitchell Schwartz or Andre Smith, fantastic. They could get a big upgrade at center in Alex Mack of the Cleveland Browns or a better left guard in Alex Boone of the San Francisco 49ers. But no matter if Laremy Tunsil winds up the No. 1 pick or not, the Titans need to add at least one proven NFL player who can help lead this group. Whatever they do at running back won't matter if they don't address the O-line, and the team has said keeping Marcus Mariota from the sort of pounding he took as a rookie is its top goal.

Priority No. 2 -- Sign Tashaun Gipson: The Browns' free safety saw his play drop off some in his fourth year, but he was hampered by an ankle injury. Pairing him with last year's strong safety acquisition, Da'Norris Searcy, would give the Titans a solid duo in the middle of the field and let them focus on cornerback, nose tackle, outside linebacker depth and perhaps an insider linebacker upgrade on Wesley Woodyard as they move forward.

Priority No. 3 -- Sign Rishard Matthews, provided the price is right: There are no clear No. 1 wideouts available in free agency, and it's always dangerous to look to a No. 2 guy and expect him to grow into a lead guy. But the Titans need more than what they have, and I am intrigued by Miami's Matthews. He ran a combine 4.62 40, yet averaged 15.4 yards per reception last season, better than some very notable faster guys -- Odell Beckham Jr. (4.43), A.J. Green (4.50), Amari Cooper (4.42) and Emmanuel Sanders (4.41) among them.

Priority No. 4 -- Shore up the interior run defense: The Titans won't be in their base defense a bunch, but when they are, they need to make the middle less enticing for opposing running backs. The Titans allowed 4.52 yards per rush up the middle last season on first and second down, 27th in the NFL. Damon Harrison of the New York Jets or Ian Williams of the 49ers could really help that cause. The Titans' two nose tackles from 2015, Al Woods and Sammie Hill, are free agents. At the very least, the Titans need to re-sign Woods.
