The St. Louis Rams badly need a wide receiver. The Dallas Cowboys could definitely use a cornerback.

It just so happens that, where the Rams draft, both top-flight receivers — A.J. Green and Julio Jones — are expected to be taken. And where the Cowboys pick, top corner Patrick Peterson should be long gone.

Even if the Cowboys prefer to take an offensive tackle in Round 1, they’d be better off trading back several spots. The No. 9 hole appears to be useless for them.

Which is why it isn’t surprising to hear that the Rams are considering trading Dallas for that ninth selection. St. Louis would then leapfrog Washington and Detroit for Jones, while the Cowboys would still have a chance to land a corner like Prince Amukamara or Jimmy Smith or a tackle like Tyron Smith or Anthony Castonzo with the Rams’ 14th pick.

ESPN’s Todd McShay said this morning on SportsCenter that he’d heard rumblings about such a trade. Unfortunately, though, it won’t be as easy as it sounds. While a work stoppage continues, no players or future picks can be traded, so teams will likely be forced to deal picks for picks.

Still, if there’s a will there’s a way. And if both teams see the swap being beneficial, they should make it happen.

The way I see it, the Cowboys would surely make the move. The Rams, though, would likely have to surrender two later picks in order to climb five spots. Considering that there’s still a chance Jones will be gone by then — we have him going sixth in our latest mock — that’s quite a risk. Plus, there’s always a chance he would’ve slid to St. Louis at 14 anyway.

Oh, how I love draft speculation.
