Straight up, I love Austin and I'm really excited about his potential as a Ram.
That said, if it could be a straight swap I think I would.
I really do like the size/speed combination of Patterson. I think he's a bigger more intimidating Tavon. His impact on ST is just as great, and I think if the Vikings force fed him like the Rams have (finally) started with Tavon, they'd see a similar impact.
But I honestly really like Tavon and I'm ecstatic that he's starting to show up in the game. I wish they'd have done this from the get go.
