CAP only team

[bucs34rules]

I've been trying to make up this team for BigPlayKiller's league next season, but I don't know exactly what my defense should be made up of. I usually throw about 70% of the time as I only run when I have to on short yard situations. I really want my HB to break tackles while getting away from defenders. I'm trying to run a 3-4 defense that must be opportunistic in causing a lot of turnovers and defend the run extremely well. Here's my team so far:

G) QB (Scrambler, Leadership, Clutch)
? - Defense

S) WR (Speed Burner, Soft hands)
HB (Speed Burner, Battering Ram)
? - Defense

B) CB (Coverage Bonus)
OLB (Closing Speed)
OLB (Closing Speed)
WR (?)
TE/WR? (?)
FS (Speed Burner)

Generics: QB-Pocket, HB-Balanced (for Leroy Green), WR-Possession, OL-Pass Block, DL-Pass Rush, LB-Pass coverage, CB-balanced(for Terry Supernaw), Safeties-balanced (I really seem to like Killam - SS, but I might have to get a better SS for run coverage?)

First, would it be better to have 3 WRs or 2 WRs/1 TE for my aggressive Vertical Offense? Second, I'm trying to find a leader on defense, so what would you guys suggest? Finally, what should I put on my Bronze WR's so they could have the best hands possible while having decent to good speed?
