Tbh Ligthart is a rider with a good sprint. Not really a sprinter....someone that contends a bunchsprint. He's someone that survives climbs pretty well so mostly a contender in the not all too hard hilly stages where a group of 40 riders sprint for the win. Too bad Sagan will also be there in those stages
He won the dutch championship winning the sprint of a group of 7 riders and he won the Hel van het Mergelland when a group of 26 riders sprinted for the finish on a slightly uphill sprint. He beat riders like Samuel Dumoulin and Visconti there so that's not too bad.
Imo he doesn't really belong the previous mentioned shortlist of sprinters that are left.
