History. They just don't want anymore interactions with him.
I've advocated for him on his talent.
I'll put it this way... I've got kids with the same issues, but thankfully not nearly to his degree, which is... his "I figured" is busted. Any statement he'd make in his head or out loud was generally wrong off the football field. The reason I've been more emphatic lately about his chances is that after looking really good in 2016 preseason, he realized this and did some intensive in-patient rehab to help repair some of that.
Even when looking at his 2016 preseason, there aren't 5 WRs in the NFL who have his combination of speed, hands, route running ability and best of all, his ability to adjust to the ball while boxing out the defender. He might be the best in the league at that bit.
I mean, when he gained over 1600 yards in 14 games, if you actually look at the passes he caught, FAR TOO MANY were badly inaccurate passes where it was solely Josh Gordon's catch radius that makes that play a great play.
Now, I'm not trying to be belligerent about this like @InnovatedMind (sorry, brother, but we're all just talking and your advocacy is a bit "in your face"), but I do agree that both his level of talent is undeniable, his ability elevates the QB he's playing with by a large margin and, as I've said repeatedly, it seems like he's turned the corner on his issues.
Josh Gordon is EXACTLY the kind of next level of talent that the Patriots will send a 5th or 6th rounder for and use him and his superlative talents to win another Championship while the rest of the league says, "who knew?"
Sorry. It's just not that hard to figure out. If he's as squared away as his agent says, (and again, it would be career suicide for both the agent and Gordon if his agent were lying about his sobriety and seriousness about Football), then it's incumbent on teams to take advantage of this.
The Patriots are constantly taking advantage of stuff like this. Heck, they picked up Michael Floyd from AZ and while he wasn't fully in the mix, he threw some excellent blocks and contributed to their run. People said Randy Moss was done or at the very least wasn't worth the heartache and he had a record setting year with the Pats.
I'm done...done, done, done with the Pats being the only team that takes advantage of prime opportunities. IF... IF Gordon is squared away like it seems (and I know many don't buy it and that's fine), but IF he's squared away, he's the kind of difference maker that Goff in his second year and his first in this new offense would desperately need to gain the confidence he needs to become the franchise QB he can be.
Woods is very good, but the combo of Woods and Gordon for our young QB would be next level. Add in Tavon, Higbee, Cooper and let's not forget Gurley and Goff would have all the weapons he needs AND an offense in which to fully utilize them.
