NFL Odds 2019: Nick Bosa, Quinnen Williams Early Defensive ROY Favorites

Nick Bosa and Quinnen Williams opened as the co-favorites to win the NFL's Defensive Rookie of the Year award in 2019.

The Caesars Palace sportsbook listed Bosa and Williams at +400, a good distance ahead of Ed Oliver at +550 and Devin Bush at +700.

The San Francisco 49ers selected Bosa with the second overall pick of the 2019 NFL draft, with the New York Jets taking Williams one pick later.

Talent-wise, little separates Bosa and Williams. Bleacher Report's Matt Miller listed Williams at No. 1 and Bosa at No. 2 in his final big board heading into the draft.

Based on their respective positions, though, Bosa arguably deserves a slight edge in the defensive ROY race. He will be coming off the edge for San Francisco, while Williams is likely to line up in the middle of New York's three-man defensive line.

Since 1990, only four defensive tackles have won the award: Aaron Donald, Ndamukong Suh, Tim Bowens and Dana Stubblefield. That doesn't bode well for Williams, who might struggle to compile the kind of stats that would impress the voting poll.

Bosa, on the other hand, will be one of the 49ers' main pass-rushers along with Dee Ford on the opposite side of the line. The former Ohio State star will be making the highlight-reel hits on the quarterback that get replayed over and over again throughout the year.

For the time being, Bosa's older brother Joey can maintain bragging rights. Joey was the defensive ROY in 2016 and a Pro Bowler in 2017. Nick may not need too long before he matches those achievements in the NFL.
