Teuns is known to be everything but a teamplayer.
I agree about the Van Wilder/Jorgensen part tho. Those guys have way too much talent to just beings doms for Remco, they need chances for themselves so you need others to do the dirty work for Remco. Problem probably still is budget. You need a really good climber that has been a leader in the past, and thus has tried to get results but can't win anymore and would be happy with being a last man for someone who can actually win. Problem is to make those guys happy being a dom you still need to pay them as a leader.
I don't even know if there's anyone free who fits that role.
Sivakov? Probably still wants his own chances, I wouldn't be surprised if some French team overpays him.
Hugh Carthy? He's always really good in a 3rd week out of nowhere.
Michael Storer? Not that great at FDJ, but did a really good job at the Tour for Gaudu last year.
Geoffrey Bouchard could maybe be decent? but not as last man ofcourse.
Leknessund would be good in a train I think?
What about Lafay?
