I could also spout off a laundry list of WW RBs that got starts as well but no point.
If this improves his lineup then I get the move I just think there could have been value.
WW RBs don't apply the same way here, because to replace Ryan Mathews they have to not only play, but they have to actually be good. To replace Joe Flacco all a QB literally has to do is play. In the current passing era if they're on the field it's almost impossible for them not to be within a point or two of what Flacco is putting up, if not performing better than him.
Above we listed off about 8 guys that were probably on the WW and either outperformed Flacco or were within a point or two per game of him. There's not a single WW RB that outperformed Mathews and not a single one within a point or two per game of him.
The closest we can get at RB is probably Rashad Jennings who was 2.5ppg behind. After that, Andre Ellington might have been available at 3.1ppg behind. Beyond that we're looking at almost 5ppg behind for LaGarrette Blount even counting his 31 point game in week 17 that most people didn't get to use.
In our league last year, Flacco scored 253 (one of his worst seasons) and Mathews scored 170. I guess I mislead with the "FBG scoring". We use 6 pt passing TDs and -3 for picks.
It's a 47 man roster dynasty league, and QBs are most valuable. There aren't any QBs available on the WW. Here are some of the top available names:
Kellen Clemens
Tarvaris Jackson
Jeff Tuel
Matt Simms
So basically garbage.
It's a superflex league, but if you aren't starting 2 QBs you are at a disadvantage.
The scoring system and large rosters (though it's IDP so not as large as they seem) do change things some, but I still think it's a really bad move for the guy getting Flacco, the same way I'd say that trading Julio Jones for Ben Tate isn't a good trade just because the guy getting Tate needs a RB.
I'm sure the QB WW looks bare now, but that will change during the season as some truly random guys get a shot every year. I'm sure if you'd given me the best available WW QBs entering last year you wouldn't have even bothered listing guys like Jason Campbell and Matt McGloin, yet there they were, matching Flacco step for step by about the midpoint of the season.
Flacco has a nice reliable starting gig and gives him a 6ppg advantage. That seems nice enough. But while not starting a QB at superflex may be a disadvantage, starting Joe Flacco (IE pretty much the worst QB you can get in fantasy terms) is still a disadvantage. I think I would have eaten the 6 points for 6 weeks until I could replace him and retained a higher advantage going forward. When those random 8th string QBs come in and start scoring the same as Flacco that 6ppg advantage is going to swing to an even larger disadvantage the other way as those guys sit on his bench behind Flacco (or start ahead of Flacco) and Ryan Mathews' vacated RB spot wrings hollow.
I also have much more confidence that the QB spot could be filled to Flacco's level going forward than that the RB spot could be filled to Mathew's level going forward. As mentioned above, replacing Ryan Mathews means you have to find a GOOD starting running back. Replacing Joe Flacco means you have to find ANY starting quarterback.
