Endurance Test For Near-term Performance Assessment: After coming back from the DL, Sanchez is being stressed to determine how far he can be pushed in September/October when he's "really needed". Coaching staff already knows Lowe's plateau or prioritize his testing for a future date.
LOL, I'll give you $5 if Gibbons ever publicly states this is what he is doing with Sanchez. Not to mention it isn't too bright. Oops I stress-tested Sanchez and now he's injured and done for the year. My bad!
