Just wanted to share something that I do every year to prepare me for my drafts and I'm actually surprised more people don't do it.
Say you wanna do a mock draft but you can't get in one or its late in the offseason and many people are doing real drafts and you can't get into any mocks or whatever the case may be. Anyway, just go find a mock that has already been done by cafe vets, other web sites or my favorite, "expert" drafts. So you find a mock draft you like, then just say I've got the 7th pick. Scroll down the first rd until you get to the 6th pick and then it is your turn. Make your pick and scroll down further, marking guys that are taken as you go. Then scroll down rd 2 until just before your turn and make your pick. Anyway, you get the idea, you are virtually doing a mock draft that you can complete in like 30 minutes. Also you can see what kind of team you could get if you were in the mock with the "so called experts", ESPN mocks, etc.
Anyway, try it out. You can do 3 or 4 mock drafts in a single night if you want. There are more and more mock drafts to find out on the net so you should have an endless supply of mocks to do. A buddy and I will sit down together and we will pick each others spot in the order and we will knock out mock drafts all offseason long without the brutal delays that actual mocks have. It works just as good as actually being in the original mock.
