An easy argument against Howard is that the Bills don't pass the ball enough, perhaps a better sticking point is that with the 10th pick they can potentially take the best WR in the draft. Whether that is Davis, Williams, or Ross is up to them to decide. WR feels like a much safer pick than a TE that high and would have more impact from day 1.
Any pass catcher at 10 is not my preference, not with this offense and not with TT as QB.
