That's bullshyt. Chip's entire system was flawed because it keeps the defense on the field for an unusual extended period of time week after week. I saw games were Chip's offense took 45 seconds off the game clock several times a games.
I hate coaches with no clout try to act like Belichick. Eric Mangini, Bill O' Brien, Chip Kelly

You aint Belichick.
But lets be real about Chip. Those 10 win seasons were with Andy Reids remaining playmakers. Chip got rid of all the playmakers (D. Jackson, Macklin, McCoy) on the squad and replaced them with backups. Chip was giving the power to pick his own players and he selected guys that didn't fit his dumb system and guys that are backups. He traded a 2nd round pick for Sam Bradford
But he kept Riley "racist" Cooper and tried to make him a no. 1 receiver.
Players were saying that Chip oversee what they eat and sleep patterns.
Chip didn't see that there is a huge different between college and NFL. You can treat collegiate players like that but you can't do grown azz men like. He literally treat them like fantasy players. In the NFL, your system will not function without elite players in key positions. You can't just plug anybody in and expect greatness.
