Who would I take with #20

[Roy P]

OT Bryan Bulaga - Improves run game. Ex: Jordan Gross.
OT Trent Williams - Improves run game. Ex: Jamal Brown.
DT Dan Williams - Reminds me of a DT in Minnesota
S Earl Thomas - Loves a playmaker, but worried about time in the tub. Maybe Reggie Nelson?
LB Sean Weatherspoon - My favorite player at a non-need postion. I think he's better than Derek Johnson and people wanted to draft him at #13.
LB *Rolando McClain - I see him going MUCH higher. Patrick Willis?
CB Patrick Robinson - Reminds me of Dunta, hopefully not in personality
CB Kyle Wilson - Carlos Rogers is my comparison.
DT Brian Price - Boom or Bust like Amobi.
CB Devin McCourty - Aaron Ross was drafted at #20.
RB Ryan Matthews - Laurence Maroney maybe?
