Blue Monday: Who is going to catch the passes?

Weird to see all the changes that the Colts have undergone and Reggie Wayne is still around, which is a great thing because after losing some receivers, I was wondering who would be left. I think Reggie will be a great safety net for Andrew Luck, and a guy that can be counted on to come up big for this receiving core.  You have Blair White and Austin Collie as well, but after that who else is around?  Do you think Austin Collie can hold up and have another good year like he had a couple of years ago?  Do the Colts need to go out and pick up a receiver or two?  Some questions for the receiving end of the Colts and ones that I don't have any answers for right now.
