Should I get Sanchez ?

[feyenoord]

I'm in a PPR league and did pretty bad today, this is my roster:
QB Jake Locker, Ten QB 10 points (did ok)
RB Jamaal Charles, KC RB 8 points (a little disappointing)
RB Kevin Smith, Det RB 24 points (did great)
WR Dez Bryant, Dal WR 12 points (did ok)
WR Vincent Jackson, TB WR 9 points (a little disappointing)
TE Jermaine Gresham, Cin TE DNP
FL Trent Richardson, Cle RB 4 points (shouldn't have started him)
DST 49ers D/ST D/ST 6 points (did ok, but my opponent had the Jets dst and got 22 points)
K David Akers, SF K 13 points (did great)

Bench Ryan Mathews*, SD RB
Bench Kenny Britt, Ten WR
Bench Demaryius Thomas, Den WR
Bench Martellus Bennett, NYG TE
Bench Jonathan Stewart*, Car RB
Bench Leonard Hankerson, Wsh WR
Bench Andrew Luck, Ind QB

Does this team have a future ? I know that Ryan Matthews and Britt will be back and that Richardson might get more playing time. On the waiver wire in my league they have Mark Snachez, Ogletree WR, Blaine Gabbert and Stephen Hill WR. Do you think I should trade any of my players for any of them or should I just wait and see what happens next week ?

Thanks !
