Here's a collection of grades for the Bears' expected signing of Dayo Odeyingbo, where experts are mostly positive about the addition.

Dayo Odyeingbo is easily the biggest mystery to Chicago Bears fans but definitely not a surprise to Ben Johnson, Dennis Allen and Ryan Poles.The surprise was their largest free agent contract paid out to someone with three sacks last year,

The 6-foot-6 and 286-pound Odeyingbo, 25, fills the starting spot opposite Montez Sweat once held by veteran DeMarcus Walker.
