The mock was updated today/yesterday. It says this at the end now:
FEB. 12 UPDATE: There's a new caveat, which is Philadelphia's restructuring of its mobile quarterback's contract. Nick Foles is now likely to be traded. Andy Reid used a second-day selection on him last year, so I don't see why he wouldn't do that again (he may only have to deal his fourth-rounder). If Reid acquires Foles, he'll draft Joeckel to protect him.
