He is absolutely worth a roster spot, and is actually probably someone's starter. However, as you mentioned, he production is easily replicable. Its not going to cost you much to get him, and he isn't going to be worth much to someone else in a trade. I think by betting on a guy like Housler, your realistic upside is getting a guy that, even if he achieves his most-likely ceiling, won't be really worth all that much to other owners.Wilson is a different story, as he adds a ton of value on the ground. Most TEs you find won't have some extra value that gives them a chance of being more than a middling TE1.
Take away every point Wilson added on the ground and he should still have massive value. Rookie passing TD record, 26/10 ratio, playoffs, awesome near comeback in the playoffs. Would have been worth acquiring regardless. For the record, I don't see Gresham as Housler's ceiling; I don't see 2012 Gresham as Gresham's ceiling. I greatly urge against treating TEs as we treated them 5 years ago. Greatly. There is room up at the top next to Graham, Hernandez, and Gronkwoski, and teams will eventually support more players and production like said trio. Housler's talents translate nicely to a Graham role and I am getting on at the floor. It's not likely he is ever at that level, but Arian Foster wasn't likely. If you don't like his talent, don't invest. I do and am.ETA: 6'5" 250, 4.5/40, 37" vert, high 3rd round draft pick. Yes please.
