I think you all play too many video games in dynasty mode.
Trades are not that easy to pull of in the NFL.
I actually think this is a misconception. I can't remember who I discussed this with and still had a difference of opinion on this, but the end result was that 1 of the top 10 picks was traded on average almost 2 times every year.For example 2005 - #7 Williamson, 2004 #1 Manning, #4 Rivers, #6 Winslow and #7 Williams, 2003 - #4 Robertson and #6 Sullivan, 2002 #6 Sims and #8 Williams, 2001 - #1 Vick, #5 Tomlinson, #7 Carter, #9 Robinson and #10 Reynolds. I stopped at 2000, because although a few of the top 10 picks were traded, I didn't know if they were picks traded in previous years.
To me this is a significant number of guys picked in the top 10, including the #1 twice, in the last 5 years that have been traded.
