You are ok at RB so it is not imparitive to take one at 1.01. First you look to deal down. See if 1.03 is willing to pay you somethig to move up to grab Moreno or Wells. I would shop it aggressively to the 1.02 and 1.03 owners as well as to the 1.04 owner but at 1.04 you need to be careful as you may get jammed with Brown.
I would also entrtain dealing th 1.01 for the best young WR you can get. If soemone is willing ot give you say a Roddy White then I seriously look at dealing the 1.01.
If all that fails, I would have no issues taking Crabtree at 1.01 in a PPR dynasty.
I agree with bungle... get to shopping. Make people think you're seriously contemplating taking Moreno or Wells at 1.01, even though you need more help at WR, in my opinion, than RB.
First try and shop him for a young but already established guy, like bungle said R. White or I'd look at even a S. Holmes or V. Jackson pick up. Just something that's going to add young, legitimate youth to your WR core, especially in a PPR league.
If no takers at all, which I'd find hard to believe with how high people are on Moreno... then personally I'd take M. Crabtree. I think he's legit, top tier talent in 2 years. They're going to put the pieces around him to look like another 49er from back in the day. Your RB depth is good, especially given that your main guys are all handcuffed... but to pass up a legit top tier threat for the next decade is nothing to pass up.
Take offers, because even Crabtree is going to have a learning curve and you can get some production from day 1 from a guy that's already making his move in the NFL, but if the fish don't bite keep riding ADP and FWP in your RB core and pair up D. Bowe with Crabtree for a young, dynamic duo in not too long.
1) your RB situation ain't all that. You have a hole at RB2. You've got AP and his handcuff and Parker- and you handcuffed your RB3 with Mendenhall. You have Benson, which really means you have nothing, and Ronnie Brown, but I can't say anything about him you'd listen to since you're a Phins fan. On this roster, Moreno would be a great RB2, and give you great depth, moving Parker/Mendenhall to their more appropriate RB3 role. Furthermore, Moreno has great hands and would give you better PPR performance than AP, Taylor, Parker, Mendy, Benson and perhaps Brown.
2) If you have some issues at WR, but they'd be able to hold down the fort. Depending on what other picks you have (a slew of mid 2nds, for instance), I'd consider moving any of your RBs but Peterson, Taylor for a WR.
3) I see Crabtree eventually settling into a Plax-like role. Burress never had more than 78 receptions in a single season. In 2004 (his last as a Steeler), he had 19.9 ypc, but 698 yards; in 2005, he had 1214 yards and 7 TDs. From the 2004 to the 2007 season, he steadily became a primarily red-zone option- his ypc consistently dropped from 19.9 to 14.6 while his TDs moved from 5 to 12. During that time, his height as a player, he never caught more than 76 passes. I've never been a fan of TD-only players, given how relatively rare touchdowns are.
3) I'm a fan of going BPA in Dynasty regardless of team need. Moreno is the best talent, and he doesn't have any character issues that could shorten his otherwise-productive career. His particular situation may not have been best, in terms of immediate production, but he's the best player. As you said, Crabtree's situation doesn't breed confidence about his immediate production, either.
4) I'm not a Wells fan- don't like the "I can't play because my pinkie hurts/I have a headache" type players. Wells didn't show me enough toughness in college.
I'd say take Moreno. He's got fresh legs after playing only two seasons in college and should emerge from the RBBC theme Denver has had in the past to be the feature back. I think Wells has a great chance to put up good numbers with the offense in Arizona, but as the previous poster mentioned he lacks the warrior mentality that will be necessary when he inevitably gets banged up.
