Colts can sign first pick on Friday

According to PFT and the NFL’s Greg Aiello the Indianapolis Colts can sign their first pick (presumably Andrew Luck) as soon as Friday:

Thus, the Colts could, in theory, sign the first overall pick long before the draft happens.  NFL spokesman Greg Aiello tells us that the Colts could sign the top pick as of Friday, after a pair of coin flips lock in the draft order.

And so, theoretically, Andrew Luck and Peyton Manning could end up as teammates, after all.  The Colts can sign Luck before they cut Manning.
