These guys will definitly be drafted too high:
QB - Carson Palmer
RB - Frank Gore / Larry Johnson
WR - Chad Johnson / Plax Buress / M.Colsten
TE - Gonzo
K - Vinatieri
D - CHI
Not to be a d!ck but I disagree with most of these selections. In fact, a number of these guys may end up providing decent value

almer- very disappointing this year and may slip into the 4th to 5th depending on the scoring system. I like that pick for a guy that I believe is a top 5 QB talent.
Gore- again, disappointing year but he did prove he can stay in one piece which was my only real reservation about him. That situation is volatile but he will likely go off the board late early-mid 2nd (due to likely influx of WRs and QBs based on 2007 stats) and could provide top five pick numbers.
LJ- not crazy about the guy but could be a steal in mid-to-late 2nd.
CJ/Burress/Colston- three WRs who are having very solid years but are lost in the Moss/Edwards/TO love that is rampant in the leagues I am currently in. At least one of these guys will fall farther than they should because of injury (PB), slow starts (Colston) or other players on their team (CJ).
I agree that Gonzo may be a bit overdrafted...Wes Welker is my pick for most overrated of 2008 (and I love the guy).
