It's the season of hope in the NFL, when teams add new players through free agency and the draft, giving fans reason to be optimistic.

Buffalo Bills: LB NaVorro Bowman
2017 team: Oakland Raiders
Age heading into 2018 season: 30
A surprise playoff team in 2017, the Bills can't afford to rest on their laurels if they want to return in 2018. Linebacker Preston Brown is slated to become a free agent, and if he does indeed depart, they could do a lot worse than look at the veteran Bowman. PFF's 11th-highest-graded linebacker in 2017, Bowman registered 33 tackles against the run after joining the Raiders midway through the 2017, with 20 of those resulting in a defensive stop.
Backup signing: LB Avery Williamson, Tennessee Titans
Another linebacker who can help the Bills win, Williamson registered 27 tackles resulting in a defensive stop against the run in 2017.

Miami Dolphins: G Justin Pugh
2017 team: New York Giants
Age heading into 2018 season: 28
The Dolphins have long had a need for improved guard play. Pugh allowed only two sacks, one QB hit and 15 hurries on his 184 pass-blocking snaps, and his pass-blocking efficiency rating of 92.4 from 2017 ranks No. 7 among free-agent guards. The 2018 draft class is loaded at guard, and the Dolphins might be wise to get another guard in the draft -- even with the addition of Pugh -- in an effort to overhaul their interior offensive line.
Backup signing: G Josh Kline, Tennessee Titans
Kline is coming off a career year in pass protection in which he allowed just one sack during the regular season.
