re: Does Travaris Cadet's performance mark C. J. Spiller's pink slip?

It makes him less fast. Yes. As people age their bodies start to break down and they don't perform as well as they used to. This is common knowledge. Hall is an older player who is pretty close to retirement. His combine 40 time from over a decade ago isn't relevant.

Ingram isn't a home run threat. He rarely breaks long runs. You posted his absolute career long run. Where he was stopped short of the endzone. Outside of that the best he manages are occasional 30 yard runs.

Compare this to someone like even deuce whose season longs before his first knee injury ranged 54-76 yards. He was a true home run threat. Ingram isn't. And it isn't an insult. It just isn't the type of rb he is. No one has ever projected him as a big play threat. Except you apparently.
