Let’s dive into the expert picks.

2025 High-Upside Players

Stefon Diggs (WR – NE)

“Stefon Diggs is ready to be a CARDI BEAST after an offseason filled with drama from pink cocaine to Cardi B relationship drama. If there is one thing for sure, Stefon knows that he will have a whole new fan base of Cardi B worshippers watching him play this year and look for him to capitalize on that fact alone. Stefon has always been a player who wants the spotlight, and somehow he has brought a very large light to the now small market Patriots.”

Rome Odunze (WR – CHI)

“I’m on the Rome Odunze hype train this offseason and won’t be stepping off any time soon. Another offseason/training camp will go a long way for Caleb Williams and Odunze to further their rapport and get on the same page with offensive-minded head coach Ben Johnson after one of the least efficient seasons of 2024. The Bears added several weapons across their offense, including the line and rookie TE Colston Loveland. They’re all in on Williams, so I’m taking Odunze well ahead of his current ADP and believe he has WR2 potential.”

Tetairoa McMillan (WR – CAR)

“Tetairoa McMillan is tragically mispriced as the WR28 in ADP. McMillan could be a wonderful volume hog this year in what looks to be an ascending passing offense. Last year, in Weeks 12-18, when Young was hitting his stride, the Panthers ranked 13th in neutral passing rate. We could see that number increase this year, with a true number one option leading the way. Last year, during that same stretch, Young ranked eighth in CPOE, fifth in deep throw rate, 12th in highly accurate throw rate, and second in hero throw rate (per Fantasy Points Data). McMillan is an incredibly talented receiver who can step up quickly. During his final two collegiate seasons, he ranked 17th and 21st in yards per route run. He’s a battle-tested man coverage beater as well. In 2023-2024, McMillan had the third-most and the tenth-most man coverage targets (among FBS wide receivers) while also ranking eighth and tenth in yards per route run against man coverage (per PFF). Don’t be surprised if McMillan is a WR1/2 in his rookie season. I’ll draft him over Jameson Williams, Xavier Worthy, Zay Flowers, D.K. Metcalf, D.J. Moore, Marvin Harrison Jr., and Courtland Sutton.”
– Derek Brown (FantasyPros)

“Panthers rookie WR, Tetairoa McMillan, has tremendous upside for Year 1. Just based solely on his top-10 draft capital, one could expect T-Mac to surpass 80 catches, over 1,000 yards, and 6 TDs based on the average output of top-10 drafted WRs the past four seasons. But if McMillan can truly establish himself as the alpha in the passing attack…wheels are up. Bryce Young has shown two years in the NFL that he can support fantasy viable WRs between Adam Thielen and Diontae Johnson. In Thielen’s last six games in 2024, he averaged 14.6 fantasy points per game – a mark that would have ranked 8th among all WRs last season. Draft McMillan aggressively in 2025 over Zay Flowers, DeVonta Smith, and DK Metcalf.”
