I'm with you on this one. TO would have forced the defenses to at least commit their best DB to cover him, and that would have helped our offense that teeny bit. Without him, no defense even CARES which DBs cover WHICH Bills WRs, because none of them are playmakers (except Lee Evans on long bombs and no other types of routes).
And Chan, if I recall, named James Hardy as the guy who could simply replace TO out there. So in that regard, yeah, Chan is looking pretty stupid right now, IMO.
