Well, I tried to adjust my OP to include a poll option, but I suppose it's too late to do that, because I didn't see a way to include it as an edited addition.... so, by gut, here are the higher promising people in this event.
F. Cerundolo - goes without saying - rose petals rain on him everywhere he goes
Darderi - 'nuf said, we all know him well, waits in his bye stall to roar out at the winner of Navone and Kopriva
Baez - our new David Ferrer? A fairly dependable plugger who sinks his teeth into opponents like a bulldog on good days, like a terrier on off days - should do well, has a bye, is
awaiting the winner of JM Cerun. and the fluctuating Garin
Tabilo - ranked #42 with 3 career titles, and a Chilean to boot, should do very well here.
Tirante - Argentinian w/#76 ranking, none too stable or consistent, but has good moments, making it to the 2024 Swedish Open semi including a win over Rublev, not that that's
too astounding for anyone who zeroes in on Rublev with a passion
Hanfmann - aging (34 years) - not a bad clay player, currently ranked #90, recently beaten by brother JM Cerun. in Rio
Prizmić - exciting 20-y-old Croatian full of promise who qualified for this thing and just defeated poor old Jarry in three sets to get to R2 where he'll take on Soto or Lithuania's
hope, Gaubas, who made it to R3 in the Masters Italian Open, scything his way through Dzhumur and Shapo en route
