(March 2, 2007) -- You will see mock drafts starting to pop up everywhere now that the NFL Draft is less than two months away. That's all well and good, but just keep in mind that there is still an awful lot that needs to happen before teams can lock in on a potential first-round target.

For starters, the free agency period has just begun, and teams can certainly fill major needs by signing a veteran player. Then there is the schedule of pro day workouts that have kicked off. Especially when it comes to college prospects who did not work out at the Scouting Combine, there is still plenty to be evaluated. Finally, there are still decisions that teams need to make about their own players.

The bottom line: Matching teams with the top college players is still a tricky puzzle. So before we figure out where they fit, let's just start out by identifying the pieces. With that in mind, here is a breakdown of the top players available in the draft.

I've broken them down in tiers; 1-10, 11-20, 21 and up. For now, players are listed in alphabetic order within their tiers. This list will be updated as the draft gets closer.

First tier -- 1 through 10

1. Gaines Adams, DL, Clemson: Gaines (6-4, 250) did not lift, but ran 4.64 in the 40, had a 35-inch vertical jump, a 9-foot-11 long jump and clocked 4.36 in the short shuttle. He also worked out as a linebacker (3-4).

2. Jamaal Anderson, DL, Arkansas: Anderson (6-5 3/8, 288) was a medical exclusion and did not work out. He looks thin at this weight.

3. Alan Branch, DL, Michigan: Branch (6-5, 324) ran 5.07 in the 40, had a 27-inch vertical jump, and 8-foot-11 long jump and did 33 reps. He did not run the shuttles.

4. Leon Hall, DB, Michigan: Hall (5-11, 193) clocked 4.38 in the 40, 4.07 in the short shuttle and 6.48 in the three cone drills. He had a 37-inch vertical jump, a 10-foot-5 long jump, and also did 15 lifts.

5. Calvin Johnson, WR, Georgia Tech: Johnson (6-5, 239) ran only at the combine and will do everything at Georgia Tech's pro day on March 15 and 16. He ran 4.35 in the 40 and 1.52 in the 10.

6. LaRon Landry, DB, LSU: Landry (6-, 213) ran 4.35 in the 40, had a 37-inch vertical jump and a 10-foot-3 long jump. He did not lift or run shuttles.
