Eighty-six days removed from their AFC championship game loss at Kansas City and 140 days 鈥 depending on the schedule 鈥 from their season opener, the Buffalo Bills return to work Monday for the start of their voluntary offseason program.
Since last season ended, the Bills鈥 to-do list started with extending edge rusher Greg Rousseau, receiver Khalil Shakir, linebacker Terrel Bernard and cornerback Christian Benford, and continued with opening-week, free-agent additions in edge Joey Bosa, receiver Joshua Palmer and defensive linemen Michael Hoecht and Larry Ogunjobi.
The Bills have scheduled only six of their allowed 10 organized team activity (OTA) workouts and the program is capped by mandatory minicamp on June 10-12.
Here are six storylines:
Brady-Allen Year 2
How does the partnership of offensive coordinator Joe Brady and quarterback Josh Allen continue to develop?

Just about everything was new last year for Allen. New full-time play-caller (Joe Brady). New position coach (Ronald Curry). New center (Connor McGovern). And new receivers (Curtis Samuel, Keon Coleman and Mack Hollins).
Allen responded by increasing his passer rating from 92.2 to 101.4, lowering his interceptions from 18 to six and winning NFL MVP.

Bills quarterback Josh Allen, the reigning NFL MVP, gathers his teammates before January鈥檚 AFC championship game at Kansas City. The Bills start their voluntary offseason program on Monday.
Minutes after the awards show Feb. 6 in New Orleans, Allen already was thinking ahead to his second offseason working with Brady. Take stuff out. Put stuff in. Fine-tune the scheme.
鈥淚鈥檓 so excited to get another offseason from Joe and learn a few more concepts we鈥檙e putting in and get back to work,鈥 Allen said.
Brady-Allen back in the lab, with the same offensive line returning, could result in another boon for the Bills鈥 offense.
Kincaid, Coleman strides
How will tight end Dalton Kincaid and receiver Coleman respond after slow finishes to 2024?
The Bills need them to respond like the late first-round pick Kincaid was in 2023 and the high second-round pick Coleman was last year.
Midseason injuries derailed last season for both players.
Kincaid (pre-knee injury): In 10 games, he had 34 catches for 356 yards, two touchdowns and five explosive receptions (gain of at least 16 yards).
Kincaid (post-injury): In six games, he had 16 catches for 163 yards, no touchdowns and two explosives.
Coleman (pre-wrist injury): In nine games, he had 22 catches for 417 yards, three touchdowns and 11 explosives.
Coleman (post-injury): In seven games, he had 10 catches for 165 yards, one touchdown and three explosives.

Buffalo Bills receiver Keon Coleman had only one touchdown catch in seven regular-season/playoff games last season following his wrist injury.
Allen has complete trust in Shakir (team-high 76 regular-season catches) and tight end Dawson Knox (eight catches of at least 20 yards) and it鈥檚 up to Coleman and Kincaid to use the offseason program to establish that kind of you-can-lean-on-us-too rapport.
Cook鈥檚 presence
Will running back James Cook be around this spring?
Cook is disgruntled about not getting an extension like his fellow 2022 draft picks Bernard, Shakir and Benford. Should he be? His production merits some kind of financial security. But should he be surprised? Hardly.
Everything until June 10 is voluntary so Cook can come and go as he pleases without being fined. Expect him to be here for mandatory minicamp, though, to avoid fines of $16,459 (first day), $32,920 (second day) and $49,374 (third day). Even receiver Stefon Diggs and cornerback Rasul Douglas would show up for that.
Cook is due a $5.271 million base salary this year, up from $1.16 million last year when he tied for the NFL lead with 16 regular-season rushing touchdowns and ranked 16th with 1,009 rushing yards and tied for 19th with 207 carries.
If Cook attends, it would be a good-faith act and frankly, he doesn鈥檛 really need much on-field work, which would allow second-year back Ray Davis to get extra snaps.

Buffalo Bills linebacker Matt Milano has played only 12 of a possible 39 regular season/playoff games in 2023-24 because of injuries.
Expectations for Milano
What can be expected from linebacker Matt Milano?
Whatever the Bills get from Milano will be a bonus.
Milano turns 31 on July 24 and played only 12 of a possible 39 regular-season/playoff games in 2023-24 because of broken right leg (2023) and left biceps injury (2024).
Only a contractual haircut, a reduction of nearly $3.6 million, equaled his return; minus the pay cut, Milano likely would have been a post-June 1 release.
鈥淲e have no doubt that he鈥檚 going to bounce back,鈥 general manager Brandon Beane said last month.
Dorian Williams replaced Milano last year and led the Bills with 114 tackles, but if Milano is healthy, he will remain a starter because of his ability to play the pass and run.
Bishop鈥檚 opportunity
Can Cole Bishop start his path toward starting at safety?
If he doesn鈥檛, the Bills have a problem.
Bishop was drafted in last year鈥檚 second round (No. 60 overall), but a training camp hamstring injury prevented him from competing for a starting spot. In 19 regular-season/playoff games, he started five times and totaled 53 tackles. The Buffalo News鈥 game charting booked him for six missed tackles.
Bishop proved to be a good tandem with Taylor Rapp and that should be Plan A for the Bills, who re-signed Damar Hamlin (one-year contract). Hamlin 鈥 14 missed tackles last year 鈥 is better off as a fill-in player.
The offseason program is impossible to evaluate a player鈥檚 physicality (no pads), but the next month-plus will be a chance for coach Sean McDermott and defensive coordinator Bobby Babich to evaluate Bishop鈥檚 grasp of the defense and his communication with Rapp.
Cornerbacks emerging
How big of a concern is the cornerback spot?
A significant concern until the Bills show otherwise.
Let鈥檚 not get carried away with the return of Dane Jackson and Tre鈥橠avious White, who spent 2024 with the Carolina Panthers and Los Angeles Rams/Baltimore Ravens, respectively. If they are forced to play significant time this season, that is suboptimal.
Cornerback should be a priority in Thursday鈥檚 first round (No. 30) or Friday鈥檚 second round (No. 56 or 62).
The Bills should feel comfortable with Benford at one outside spot (five regular-season interceptions in 39 games) and Taron Johnson at the nickel, but the other outside spot remains vacant.
