There very well may be a rookie wage scale for 2011, too. If the CBA gets done before the draft, there will be.
Also, if you're an NFL owner, and you select a guy #1 overall this year you know a couple of things:
-you hold his rights for the next football season
-there won't be football until there's a new CBA
-when there's a new CBA, there will be a rookie wage scale
-you have until training camp to get this kid signed.
Knowing all of that, why does anyone think an owner will pay a giant contract, like last year, to the #1 overall pick, even if a CBA isn't done by April. There is NO reason to sign the kid before the CBA; and the CBA will limit what the kid can make. So the rookie wage scale, in effect, has already cost the kid money. Even if the wage scale isn't in effect, the leverage is ALL on the team. They can offer him a modest contract and say "sign it, or re-enter the draft next year and you'll get a contract under the rookie wage scale and make even less."
So he's probably barely losing anything by waiting a year. Especially considering that the guy picking first this year (owner Jerry Richardson) HATES spending money and is at a lower-revenue team. There's no way Luck was getting a Bradford contract this year. There's just no reason to give him one.
