It's not all about getting an elite guy to go out there and crush the secondary (although that's nice). It's about scheme; our run game predicates how open our guys get downfield. Personally, I'd like a taller, bigger guy like BMW was that can run underneath and intermediate stuff and dominate one on one matchups. It would also be nice if our TEs continue to progress and get better (read: more consistent). You can only send so many guys deep. Say we sign Wallace; do we just run Rice on the other side and run them both deep ? Rice becomes an intermediate/underneath guy ?
The more talent and speed you have at the WR position, the better. It not only gives the QB more options, but it forces the defense to not cheat and double cover Rice because they know we don't have a burner that can get behind the defense.
Tate's sneaky quick, but he's not a burner like Wallace that can stretch the defense on a regular basis.
It's a fun conversation to have, and I don't think anyone's saying to break the bank for a guy like Wallace. Probably a moot point, I'm sure there will be a stupid team like the Jets or Raiders that'll pay him $10,000,000 a year.
