Mock drafts are a poor way to evaluate talent. I'd be much more interested in if their projections of talent (i.e. Kiper's Big Board) gets the players general draft area right. For example, did Kiper's top 10 get drafted in the top 20, did his 2nd 10 go somewhere between 1 and 30, did his 3rd 10 go somewhere between 10 and 40, etc. Some teams will make reaches that distort things, but for the most part a talent evaluator (particularly one profiting from their "insight") should know that Alex Smith is contending to be the top pick overall as opposed to a 3rd round choice, which is where Kiper had him March 1 of that year.
