Very solid team. RB's look great, and wide receivers are solid also. Bress is a stud, and I wouldn't worry about your TE. After the first two tiers of TE's (Graham, Gronkowski, Witten, Davis, and Gonzalez) there's a huge dropoff and most players after that are pretty equal. This would be a good team in a 10 team, so you know you did well seeing how this a 12.
The only area that if you wanted to beef up a little would be TE. I think Myers will have a decent year and Manning hasn't really ever had a good TE to work with. And with the RB in NYG, still have my doubt on Wilson, Gresham would be an upgrade but just slight.
Or you can drop one your WR and pick up an extra TE for your bench. Play them against the schedule to maximize your points. Stevie Johnson really doesn't have anyone throwing to him this year and BUF is a solid run time.
Qb - Brees is top 5 QB so good job there, might need a backup but he's obvioulsy solid.
RB - Martin = beast, Jackson is a potential beast in a great ATL offense (he is older though), Mathews also is a beast potentially, but has to stay healthy, wouldn't bet on it though. Past that Tate, pierce and Moreno are just meh.
WR - They're Ok, not great. Colston should have decent year but Brees spreads ball around a lot. The rest of your WRs have some upside, but probably not elite.
TE - Ok, not great.
You're strong at QB and RB, two positions that's nice to be strong at. Could use some WR help I guess
QB: Drew Brees RB: Doug Martin, Steven Jackson, Ryan Mathews, Ben Tate, Bernard Pierce, Knowshown Moreno WR: Marques Colston, Antonio Brown, Cecil Shorts, Steve Johnson, Emmanuel Sanders, Kenny Stills TE: Brandon Myers DEF: Patriots K: Janikowski
very solid team until ya get to the te position but unless you get graham theres not a huge drop off anyways. for me id still try to package shorts or stevie and tate and try to upgrade the te position thou or try for a higher tier wr. the guy that has foster would prolly be your best chance for packaging tate and someone.
