Two-star Scoobs: Oregon State

We all know that recruiting is an inexact science, and Arizona linebacker Scooby Wright proves the point on his Twitter handle TwoStarScoob.

The true sophomore unanimous All-American became the nation's most decorated defensive player, winning the Lombardi, Nagurski and Bednarik awards. However, when he was known as "Philip" Wright as a high school senior, he was rated just two stars by Rivals.com and Scout.com. ESPN.com gave him three stars.

Funny thing is, for every player who is celebrated at every level all the way to NFL super-stardom, there are more cases of guys coming from nowhere to become stars. Or at least key contributors.

That is the purpose of this series. We'll run through each Pac-12 team and highlight a player who was low on star rating when he arrived on campus but became a critical guy.

Next: Oregon State.

Two-Star Scoob: TE Connor Hamlett

Recruiting ratings: ESPN.com: two stars; Rivals.com: two stars; Scout.com: No. 99 TE in the country

Recruiting analysis: Hamlett generated very little recruiting interest outside the Pacific Northwest and was a bit a tweener prospect because of his 6-foot-7 frame. From the ESPN.com analysis: "While tackle may seem like the best long term fit, he has good enough hands that you could see him staying at tight end."

On campus? He remained at tight end and carved out one of the best careers for a tight end in school history. He started 29 games and finished with 104 catches, which ranks third among tight ends in school history. His 1,109 career receiving yards ranks fifth all-time among Beavers tight ends. As a senior in 2014, Hamlett began the season on the Mackey Award watch list (nation's best tight end), started all 12 games and finished third on the team with 32 catches for 342 yards and two touchdown receptions.
