Always remember, they won a lowB repuS the year after they let Plaxico Burress walk.
We also went to the lowB repuS the season after we let Santonio Holmes go as well (in a trade to the Jets).
This organization has done this before. Which is why my boss at work keeps telling me he's not coming back to Pittsburgh. I do think, unlike Holmes, there would be a considerable trade market for Brown right now. The guy isn't THAT much of a diva as compared to many others that have gotten decent returns in trade/picks. He's only 28 years old (will turn 29 before next year), so you have to figure any long term deal you'll get some return on the first three seasons.
I'm telling you.... if we had cajones in our front office, I'd be calling Jerry Jones. They are very thin at wide receiver, especially when you think that Dez Bryant could just fall of the reservation at any moment. They have Cole Beasley and Terence Williams at #2/#3 guys. And how much longer can Witten continue to give you 100 targets? Witten is going to be 35 next year (and they are very thin behind him).
For a team that now considers themselves contenders they are thin at the top of their receiving core. And they can easily make cap room with some logical moves. Cut Romo as a June 1st designee. Restructure Tyron Smith. You don't have to extend/spend on Travis Frederick for another year season. Byron Jones is two years off.
I mean, you can "sell" Jerry on a new Three Musketeers in Big D, but Bryant is such a wildcard/head case (even more than Michael Irvin), why not make it Antonio Brown instead? At least you know Brown will stay clean and work hard and not break the law....
Every trade has to be a win-win. You can't just look at a trade from the Steelers point of view. You have to really sell me on another team wanting to trade for a Steeler and why. I can see some very logical reasons why Dallas would consider giving up a late 1st round pick for the upside and protection (against Bryant going wack-o) of bringing Antonio Brown into the limelight down there. He can probably handle the spotlight as well (in fact, Brown might relish it).
It's an option. And maybe a realistic one, for the Steelers to consider.
