in one of the leagues I played in last year, Brees scored 364 points and Ray Rice scored 283.
That's great and all when you look at it as pure points scored versus another player. But I look at it this way:
Let's say Brees goes 5th overall in a standard scoring league. He scored 345 in my league last year. That's an average of 21.5 PPG
Matthew Stafford will be a 3-5th round pick in most leagues I'd imagine. He scored 275 last year for an average of 17.18 PPG
Thats a difference of roughly 4.5 PPG.
That being said, let's look at 1st and 4th round RBs by comparison.
Ray Rice scored 222 in my league last season for an average of 13.8 PPG. He will go in the mid-late first round in most drafts this year.
Now, in the 4th round, the RB pickings will be slim. Most leagues require you to have 2 starting RBs. All your top tier guys will be gone and you'll have to hope to get a guy like say, BenJarvis. He scored 151 last season for an average of 9.1.
Thats a difference of 4.7 PPG.
In my opinion, if you skip a top tier RB (of which you generally need to start 2), in favor of a QB who will net you only 3-5 PPG more than a 2nd or 3rd tier guy, you hamstring your team. You points per position started will be down overall.
I don;t know about you guys, but I would much rather have:
Here there is no "reaching" in the third round for a mediocre(at best) RB in the third round when you could be getting an above average WR or TE at this position.
Than to have
Rashard Mendenhall (you'll have to reach for a RB2 in round 3 IMO)
Reaching for QBs, more often than not, hampers your team in the long run over a season IMO. I've seen it happen many times and I've even done it a few times before I learned my lesson. Now that I ignore QBs in the first round as a rule, I have made the playoffs 4 straight seasons and won the league one time.
