Yeah I feel like there's something missing. The result isn't surprising at all, and the word "typically" allows for exceptions, so I have no beef with the conclusion. Just wondering about all the data.
Basically, though, a RB would have to be an outstanding performer throughout his rookie contract, stay healthy, and be a deciding factor in a lot of games for those four years in order to justify using a first round pick on him. Once he's out of that low cost rookie contract, there's no sense paying for his decline. And the percentages say that most players won't live up to that high standard throughout their first four seasons, especially at such a physically demanding position, so the odds are stacked against you if you spend a first rounder on a RB.
Hey look, another bitter Patriot writer:
Yes, because as we know, DeflateGate and Spygate provided Brady with extra motivation, REVENGE, and just rocketed himself to Super Bowl victories those sea.....oh, wait....
(and some day they'll come to realize that success automatically does not equal hatred. It's when arrogance and shadiness begin to rub off and wear thin, for one. If so, everyone would hate the Spurs of the past 20 years, for example.)
After watching the video on the link, and seeing his reaction I 100% believe that he walked out due to overhearing Chris Harris. IMO post game interview rooms should not be set up where you can hear the player in the opposite room better then you can heard the player you are interviewing.
