Should I do this trade??

[The U]

PPR IDP keeper league with huge lineups, not much left on WW.
Lineup includes: 2QB 3 RB 4 WR 2 TE 1 WR/TE 1 K 3 DL 3 LB 3 DB
Quarterbacks score the most points, and I am down to a Rookie QB(injured/bye) and Cassel...

I've been offered MCNabb and D Lee for M Bell and O Daniels...I've lost two straight now, and possibly my 3rd game. Daniels is #3 in points for TE. Should I do this trade?

My team:
Cassel Stafford
PT, Grant, F Jackson, Bell, McClain, Harrison, Norwood, Forsett
Marshall, Housh, Cotchery, Henry, Henderson, Britt, Urban, Murphy, Clowney
Daniels, Lewis
Crosby
J Allen,S Rogers,J Hall,T Brown, Geathers
Rudd, DJ Williams,J Mayo,S Cooper, T Howard
B Meriweather, D Revis, A Elam, Weddle, J Byrd

I think you almost have to do it to survive. Mcnabb can be a top 10 QB easily from here on. Losing owens sucks but Bell is only going to get limited carries behind PT. M Lewis is doing fairly well this year.

I'd do it.
