After watching Jr. working just to keep that car on the track at LMS it's clear to me that he is a talented driver. That car was almost undriveable.
How many times has he been running well, come in for a pit stop where they made a change or two and then he's running backwards? Usually it's every race. Unless Jr. is giving them bad info about the car, it's not his fault.
The team has problems. Jr. has made a few pit road mistakes this season, but the 88 team needs Hendrick coming in and making some changes, starting with Eury Jr. There's no way Jr. would fire his cousin, but it needed to be done.
