They are favored in every game – the only team in the NFL that can say that. They are expected to cruise to another AFC East championship. They have the league’s MVP at quarterback. Expectations are sky-high for the Buffalo Bills. Period. Still, nothing will be handed to them. In order for the Bills to reach those lofty expectations, they’ll need every player on the 53-man roster to contribute in some way. Of course, every player has his own expectations. Experience and salary shape those expectations. Here – in alphabetical order, not necessarily order of importance – are 10 Bills with the most to prove as training camp begins:
1. Cole Bishop

A second-round draft pick in 2024, Bishop suffered a shoulder injury in training camp last year that surely slowed his development. Forced into action because of an injury to Taylor Rapp in Week 5 against Houston, he got beaten deep – a moment that seemed to stick with the coaching staff. He also let 160-pound Chiefs receiver Xavier Worthy wrestle the ball away from him in the Bills' AFC championship game loss. Still, Bishop will get every opportunity in training camp to show he has grown from those moments and is ready to be a starter. His No. 1 priority for camp: Stay healthy.

2. Joey Bosa
Let’s just get this out of the way right now: It was a horrible look for Bosa to be hurt during the spring, no matter how minor his calf injury was. For a player signed to a one-year, prove-it contract mainly because he’s been unable to stay healthy the past three years, Bosa did not get off to a great start in Buffalo. Of course, the Bills need him healthy in January, not June, so all will be forgotten if that happens. At 30 years old, Bosa will want prove to he still has productive years ahead of him.

The Bills will count on second-year receiver Keon Coleman as one of their top outside threats this season.
3. Keon Coleman
The Bills were blunt in their assessment of Coleman’s up-and-down rookie season. Their main takeaway: Coleman did not return from his November wrist injury the way the franchise needed him to. To his credit, Coleman owned it, and he has seemingly put the work in this offseason to be stronger in his second year. It matters to him, which is the necessary first step. With Amari Cooper no longer in the picture, the Bills are counting on Coleman to be their primary outside receiver. A lot is riding on how he develops within that role for the offense.
4. James Cook
His agents might dispute this, given that Cook is coming off a season in which he tied a single-season franchise record with 16 rushing touchdowns and was named to his second straight Pro Bowl. Nevertheless, the Bills clearly need to see more, since they have failed to this point to give Cook the pay raise and contract extension he’s seeking. He played less than 50% of the offensive snaps last year, so the first step is seeing that number increase. Whether it’s for the Bills or another team, should he reach unrestricted free agency, Cook will be eager to show he is worthy of an eight-figure contract.
5. Ray Davis
So what happens if the Bills decide not to pay Cook? The No. 1 option on the roster right now would be Davis, who performed well in a featured role in Week 6 when Cook was out of the lineup against the New York Jets because of an injury. Davis was thought to be a between-the-tackles runner when he was drafted, but he impressed with his receiving ability and overall elusiveness – albeit in a small sample size. Before letting Cook walk, the Bills must be confident Davis can handle starting reps at the position.

Bills tight end Dalton Kincaid was the team's third-leading receiver with 448 yards in his second NFL season.
6. Dalton Kincaid
A pair of knee injuries led to a downturn in Kincaid's second season. He had a chance to make a play in the AFC championship game on the Bills’ final offensive drive, but he couldn’t make what would've been a tough catch. That moment has stuck with him this offseason. He stayed in Buffalo, working with the team’s strength and conditioning staff. Similar to Coleman, he has seemingly done the right things this spring, but he has to show it this fall. With a decision on the fifth-year option on his contract looming next year, Kincaid has to deliver on the promise he showed as a rookie.
7. Matt Milano
He has been one of the great defensive players during the Sean McDermott era, but the Bills reworked Milano’s contract this offseason, shaving a year off the deal. That means he will become an unrestricted free agent after this season. Milano turns 31 later this month and is coming off back-to-back seasons in which he dealt with major injuries. Bills general manager Brandon Beane said the team is open to bringing Milano back, but the way in which his contract was reworked suggests he will need to prove he can stay healthy before the team follows through on that possibility.

Bills defensive tackle Ed Oliver enters his seventh NFL season with 27 career sacks.
8. Ed Oliver
Seemingly an annual choice for this list, Oliver has a maddening habit of dominating games, at times, and disappearing at others. His cap hit of $11.2 million is fifth highest on the team, and it balloons $24.195 million next year. The Bills need to get more out of Oliver in the biggest moments. One potential way to do that is to ease his workload a bit, which has hovered near 70% of the defensive snaps. The addition of T.J. Sanders via a trade-up in the second round of the draft could be the right way to do that.
9. Curtis Samuel
A couple touchdown catches in the postseason saved what was an otherwise underwhelming first year in Buffalo for the veteran receiver. Samuel dealt with numerous injuries that likely impacted his performance. To his credit, he never publicly complained about his role, even when his playing time and target share failed to live up to what was expected when he signed. There is still reason to believe that Samuel can have a meaningful role in the offense given his previous history with coordinator Joe Brady. If that doesn’t materialize, however, he could be a cap casualty next offseason.
10. Mitchell Trubisky
Here’s the good news when it comes to Trubisky: The Bills haven’t needed him for meaningful snaps in his two seasons with the team over two different stints. Here’s the bad news: His performance last year in training camp and the preseason left observers concerned about what might happen if he has to take those meaningful snaps. Trubisky has legitimate competition for the backup role in Mike White. The Bills could save $1.5 million against the 2025 salary cap by cutting Trubisky at a time when every dollar matters. The backup job certainly won't be handed to him.
