After staying on top of the latest news and developments throughout the preseason, it's time to present my one-man mock draft. Keep in mind these are not player rankings, but my own personal view of where players should be selected in the first six rounds of a 10-team league, based on needs and draft flow.

The one-man mock is based on standard performance scoring with a starting lineup of 1 QB, 2 RB, 2 WR, 1 TE, 1 FLEX, a D/ST and a kicker. You won't see any of the last two positions here as I usually leave them for the last two rounds without picking backups.

Round 1

1. LaDainian Tomlinson, RB Chargers: The perennial fantasy superstar may think he has a lot to prove after how the playoffs ended last season.

2. Adrian Peterson, RB, Vikings: Defenses simply can't defend the Vikes with an "eight in the box" approach. A great young runner behind a superb offensive line, he allows Minnesota to impose their will on opponents while fantasy players rejoice.

3. Tom Brady, QB, Patriots: There is no obvious reason to expect a significant drop-off. I need to hear more than past statistical comparisons to other QBs, which don't mean much when you consider Brady has his top receiver back and locked in for 2008.

4. Randy Moss, WR, Patriots: Like Brady's owners, you're going to be hounded with trade offers all year long. Everyone wants him, but you will have him if you grab him here.

5. Joseph Addai, RB, Colts: Versatile and a focal point of a high-powered offense, he is a fantasy superstar.

6. Brian Westbrook, RB, Eagles: Has become highly respected for his willingness to take on a heavy workload and play through injuries, and another fine season is ahead.

7. Steven Jackson, RB, Rams: Would rank higher if the holdout hadn't caused him to miss time in camp.

8. Reggie Wayne, WR, Colts: There is a bit of a drop-off at RB after Jackson, so shoot now for the elite WR.

9. Terrell Owens, WR, Cowboys: Still in great shape, he remains a terrific high-level pick in yearly leagues.

10. Marshawn Lynch, RB, Bills: After an impressive rookie year that really displayed his potential, Lynch becomes more of a consistent all-around fantasy producer this year.

Round 2

11. Peyton Manning, QB Colts: The knee issue drops him out of the first round, but is not major enough to let him slip too far.

12. Clinton Portis, RB, Redskins: Looks like the Washington offense won't struggle under a new regime, and that is good news for Portis.

13. Marion Barber III, RB, Cowboys: I like him a lot myself, but he isn't quite first round material. Some are taking him in the top five, which is a bit too early. Barber is not a guy who will break off many big plays, and he will share some carries with Felix Jones.

14. Braylon Edwards, WR, Browns: Derek Anderson is for real, which means Edwards is here to stay as among the best at his position.

15. Marques Colston, WR, Saints: He is underrated by many fantasy owners and a fine value choice if you get him any later than this.

16. Andre Johnson, WR, Texans: If he stays healthy, Johnson will have a monster year with QBs who can now get him the ball consistently. Just don't wait too long to back him up with an "insurance" pick.

17. Frank Gore, RB, 49ers: Could disappoint at times as the weak supporting cast drags him down, but overall numbers will still be very good.

18. Larry Fitzgerald, WR, Cardinals: Fitzgerald may have not delivered his best season yet, and that's a very enticing thought when he is still available.

19. Torry Holt, WR, Rams: The Rams have crumbled around him before, and Holt still came through for fantasy players.

20. Chad Johnson, WR, Bengals: By the time the season starts, the offseason hoopla and ankle issue shouldn't worry you anymore. Back him up a few rounds later if you have any lingering concerns, but Johnson is simply too good to pass by at this point.

Round 3

21. Laurence Maroney, RB, Patriots: I don't care what LaMont Jordan is doing during the preseason. When the real games begin, Maroney is going to emerge as a top 10 fantasy RB. You will love getting him here or even a round later, which will happen in a lot of drafts.

22. T.J. Houshmandzadeh, WR, Bengals: Preseason hamstring problems have slightly hurt his stock for now.

23. Ryan Grant, RB, Packers: You may see inconsistency early as the offense sputters at times under new leadership.

24. Jamal Lewis, RB, Browns: Playing behind a very good line as the finisher for a fine offense gives him a very positive outlook for 2008 after he was better than expected last year.

25. Maurice Jones-Drew, RB, Jaguars: No RB in the league makes the most of every touch quite like he does.

26. Plaxico Burress, WR, Giants: As long as he avoids major injury issues, the numbers are going to be top-notch.

27. Wes Welker, WR, Patriots: Consistency is sometimes an issue, but he is a prime target in a great passing game.

28. Anquan Boldin, WR, Cardinals: He's going to show the Arizona front office that he is ticked off and will take it out on opposing secondaries.

29. Drew Brees, QB, Saints: The ultra-effective driver of one of the league's best offensive machines, he uses all of his weapons for maximum productivity.

30. Roy Williams, WR, Lions: Seems like he is falling to me later than this point in every draft.
