Personally, I would have traded him before GRob.
I admire his guts. TA is a tough little guy, and fearless. But he just has poor hands, and isn't much of a route runner. If the Rams were already a good team, a player like Austin is the kind of guy you want to add another dimension. But at his cap hit, and with the Rams rebuilding, I don't think he brings them needed value.
If the Rams can get a 3rd or better for him, I make the trade. Or, a young, high-upside veteran center, DE or corner, especially.
