4.6-4.8 is pretty good. Anything under that is exceptional...

A lot of people would say Dick Butkus. Some may argue that Ray Lewis is the best inside linebacker of all time. There have been a lot of great inside linebackers who are Hall of Famers, so it is somewhat a matter of opinion.
Chad Greenway
Tom Landry a lot of people believe Tom Landry invented the position of middle linebacker, but Bill George was playing middle linebacker in 1954 while Tom Laundry was still playing corner-back for the Giants.

Mike Singletary is considered to be the best all-time linebacker.
Jerome Boyd of the Oakaland Raiders ran the fastest 40 time for a linebacker in Oregon history at 4.33 seconds but now he plays safety, if i had to guess Demarcus Ware, Patrick Willis, and Thomas Howard have to be some of the fastest Linebackers in the NFL.

Safety or a linebacker would be a good fit
Clay Matthews played linebacker with the Browns from 1978-1993. He was a 4 time Pro Bowl selection in the 1980s.
Former NFL linebacker Paris Lenon is 40 years old (birthdate: November 26, 1977).
A good 40 time for a 10 year old would depend on their height and weight; however if they can get or under a 6 that would be fantastic.
