HTC have shown a great knack for knowing which talents to cherrypick from other people's development programs.
Recently they've been happy to let some very talented riders walk (Ciolek, Greipel, Boasson Hagen, Lövkvist) because they've been more interested in keeping the golden egg that is Cavendish - Greipel and Ciolek are very good sprinters, but they don't exactly add a different dimension that Cavendish doesn't already do better; Lövkvist, well, the team have shown time and time again that they don't care about non-sprinters except as leadouts, most notably asking somebody on the GC podium of a Grand Tour to do a turn in the leadout train. But that they let EBH walk is a bit more surprising. Goss appears to have similar upside to EBH but be more of a sprinter, so it could be interesting to see if HTC are willing to nail their Cav colours to the mast again or if there are some difficult decisions to be made by Stapleton.
