That would be nice, because I think that Hooman is a fine blocking TE, but he's definitely not fooling anyone in terms of acting as a capable receiving option.
Who knows what's going on with Keller at this point, though? If it goes another 10-14 days, I think we can safely cross him off the wishlist. My fear is that it may be too deep into camp for him to effectively pick up the system, although my opinion is that TEs are nowhere as near as complex as WRs, so I could be off with my assessment just the same.
