Where was Mayberry's Combine Invite?

Ever since the NFL Combine announced which players were be given invitations, I was shocked to see that Matt Mayberry did not receive one. Mayberry had a pretty good senior year racking up tons of tackles, has good speed, and is all around a hard worker who has good measurables. I understand that the players invited to the combine were invited on more than just statistics. However, to get a decent gauge of how Mayberry matched up with other linebackers at the combine, I compiled every linebacker's stats and compared them to Mayberry's this past season. Here is what I found:

Mayberry had more tackles than 78% of the linebackers invited to the combine

Mayberry had more sacks than 94% of the linebackers invited to the combine

Mayberry had more INT's than 94% of the linebackers invited to the combine

Mayberry had more forced fumbles than 72% of the linebackers invited to the combine

Mayberry didn't record any recovered fumbles last season but neither did 58% of the linebackers invited to the combine

Mayberry had more tackles for loss than 72% of the linebackers invited to the combine

After looking through my excel file I was shocked to see how much better Mayberry's numbers were compared to other linebackers invited to the combine. Hopefully Mayberry has a great Pro-day next week and can garner some attention from NFL scouts. Based on stats alone, he definitely should be considered in the upcoming NFL draft. What do you guys think? Should he have been invited to the combine? Should he get drafted in the upcoming draft?
