Okay in the first installment we discussed getting RBs early because this position is the most injury-prone and thus the least deep of all positions in the draft if you consider 1,000 yards rushing the standard. Some people even go so far as to draft 4 straight RBs in the opening rounds in case of injury to one of their starters.
Today lets look at filling out your roster before you achieve any depth. Some people try to get the best slot for each QB, RB, WR, TE, K, Defense/Special teams before going back and adding their backups in the later rounds. However, you will notice that the people that win their leagues dont worry about getting the best kicker or defense until they may fall into their lap in the last rounds. They make sure they are 3-4 deep at all the money positions(QB, RB, WR) before even looking at TEs, kickers, and defense/special teams. Some people even take the backup of an opponent's starter if his health is at all an issue. Talking to you Donovan McNabb. There is not a lot of depth at TE either so dont burn an early pick on one at the expense of getting a solid second WR, for example.
Try to fill in all of your weakness you see by week 4. Then by week 9 solidify yourself enough to get thru the playoffs if your league offers those. The people that win the championship dont sit on their arses with just the players they drafted before the season starts.
