Pettine was very thankful for Rex getting him where he was, and never really said a negative word about him (even on his way out the door). He just felt he could do the job better. And you're right. Rex scared no one. You know who else is still happy for what Rex did and has done for him? Jeff Weeks. Rex just doesn't have the personality to be a HC, because at some point, you have to piss some people off. By and large he's not willing to do that.
Pettine really only became truly disillusioned when Rex forced the Jets to draft Scotty McKnight. He felt that it's an honor to be drafted in the league (not to mention it's better financially than it is for a UDFA), and there were other players the Jets had higher on their board, whereas McKnight was barely even on the UDFA radar. Can you blame him for wanting to be a HC so these kind of situations would be more under his control?
The guy was a reporter embedding himself with the team, hoping to chronicle a Jet Super Bowl run. Instead he witnessed a dumpster fire. This wasn't Rich Cimini being sent in there. It was just some guy who can write. And he actually liked basically everyone in that organization. If anything he was rooting for the Jets. They wouldn't have let him do that if they didn't think he'd be fair in his reporting. I get it, he's gone and you totally don't care about him. Read the book anyways.
Slauson ended up being a great pick, but in typical Jet fashion we didn't retain him. Greene was labeled as a power back but he never pushed the pile and always got up from tackles like he was hit by a truck. The gap between him and a true power back like Ivory was vast. 1st round grade! We traded up for Sanchez to get him 5th overall, and he was a bottom 5 QB every year, and is now a career backup. In no way, shape or form was he an "above average pick". He cost us far more wins than he provided, and still is doing so on his 2nd team.
People who like baseball, like baseball, and that's never going away. The NBA could maybe overtake it one day, but MLB is still the # 2 sport in the US. People who like football are watching a sport slowly getting ruined by the people who run it, and by the violence of the game itself. It won't be around forever. Just calling baseball boring and dismissing it is a personal, subjective take. You don't like it, cool. Doesn't mean others won't gravitate towards it if football goes away. It's not a soap opera or fake wrestling. It's a sport, and a popular one that's been popular for a very long time. Much like soccer for the rest of the world.
We've seen many non-fragile players go down this year. It's really simple. In the NFL players get hurt. An injury would have cost us $8M. Would you have been OK with that happening just because we wanted to give Coples some "run"? Is he really that much of an impact player?
