I have seen a few posts that are indicating that Jags Offense is more explosive and/or better than Giants Offense.
I think the Giants are not only more explosive but are proven and have more balance and talent especially at the skill positions -
Qb - Giants - Collins over Leftwich (may be good in the future but is a rookie right now).
WR - Giants - Toomer and Hilliard over J. Smith and T. Edward/M. Hatchette
TE - Giants - Shockey over Brady (I think Brady)
RB - Jags - F. Taylor (when healthy) over T. Barber but is a close call.
Actually I am impressed with our D holding them to 10 points in their house and Giants also coming off of a bye with J. Fassel game planning over 2 weeks.
