If McVay truly believed that Austin was as special as he's spinning to the media, he wouldn't let a player like that go, especially not for a mere 6th rd pick. If the Cowboys had not offered the pick, there is a strong likelihood that Austin would just have been cut anyway, even after renegotiating to a more team friendly contract. If he really believed Austin could be that type player and the thing holding him up were the injuries, why not give him a full off season with him healthy? For us it's a low risk 6th rd pick, but makes less sense for them to trade away that type talent for a 6th rd pick. Realistically, who could they draft in the 6th rd. that could bring that talent?
It sounds like, at least to me, they really like the person, have great respect how he's handled his situation, great locker room guy, great team mate, team first guy, all good things, but also not the weapon they had hoped for on the field.
Linehan did great with Reggie Bush, but Bush had already proven himself in this league it's not like Linehan turned him around from a disappointment. Bush is a whole different type, he is/was a RB and better receiver than Austin has shown himself to be. Austin can have a role on this team, but it's very doubtful that he will suddenly become what some still envision he should be.
I get where you're coming from. But often times new regimes want to bring in their own guys. Snead and McVay had nothing invested in Austin and once they saw that they didn't necessarily need him, they moved him. He is also looking for a new contract after this season and I imagine that the success of the offense without him made him extremely expendable, thus him only going for a 6th. Again, Tavon is a weapon but in a niche role. The Rams weren't going to reconfigure their offense for him and were too successful in 2017 to worry about integrating a niche player. His athletic talent and ability are elite and they know and have said that.
Going back to managing expectations, Tavon should not have been the #8 overall pick and it was a bad pick by a bad regime. He is a round 2/3 guy who can be very effective if employed correctly. His success is almost directly correlated with how he is used. He's not a QB or MLB that has to be use mental sharpness, football know-how, and technical knowledge to succeed, it's literally just a matter of getting him in space. As long as Tavon still runs fast, is still quick, and still has natural instincts, he's going to be physically capable of being just as effective as he was in 2015. And by all accounts, he is still the same athlete.
Tavon has done enough in the league to prove he is effective with the ball in space, just look at his career highlight reel or just the 2015 season. Unless he is slower, less quick, and less instinctual than he was when he entered the league; his success will be completely up to his use. Again, he's not a QB or OT where their career hinges on what they learn in their first few years in the league. He's not a guy who necessarily has to be '"developed", he's a plug and play niche guy. The nature of being a niche player is that you don't have to stray out of your comfort zone, just go out and use natural gifts a few times a game. That ability will be there as long as his athleticism and instincts are.
As for Reggie Bush, he was a notch above bust after his years in New Orleans, it wasn't until his second team in Miami that Bush was able to be viewed as anything more than a change of pace guy. An extremely similar situation as Tavon. Reggie's first year in 2011 with Miami yielded 1,086 rush yards and 6 touchdowns, with 43 receptions, 296 receiving yards, and one receiving touchdown. It wasn't until 2013 that Bush had his career with the Lions. He had 1,006 rushing yards, 4 rushing touchdowns, 54 receptions, 506 receiving yards, and 3 receiving touchdowns.
Reggie is more RB than WR and Tavon is more WR than RB, but they are both tweeners who rely on athleticism and instincts to be explosive open field players. Both players need to be put in specific situations in order to thrive. Heck, even the great Sean Peyton couldn't do it for Reggie, it took Linehan to give him a specific role and not try to fit him in a traditional role for him to shine as an all-around contributor. Linehan's experience with this gives me a little hope that he can put Tavon in the right spots.
Again, guys like Bush and Austin are elite athletes that simply need to be used correctly in order for them to be impactful. As long as guys like that have the speed, agility, and instinct; it's gonna be up to how they're used to dictate how effective they are. Niche players rely on certain strengths to be effective in small doses, unless Tavon has lost those physical gifts, he will always be effective in the right situations. It's just up to the coach.
