The weak field thing is being overblown. Pogacar and Vingegaard have proven to be far superior to the rest of GC riders in the past years, no Vingegaard here, so not surprising that Pogacar is easily gaining time each time he tries.
It lacks depth compared to the TdF, sure, but the ones behind Pogacar are no slouches. If they were starting as TdF leaders they would be candidates for the Top 5 as well.
Thomas coming into the season could be regarded as number 4. Should have been IMO. He seems to have lost a step, first TT was bad, second decent, but not up to expectations either really. Mountains similar, Thomas a year ago here would finish the stages in second position. But even a Thomas that has lost a step is not necessarily weaker than Mas etc.
Martinez? He's finally back, after the Giro 21 I was sure he'd be a podium contender from 22. Possibly overtaking Bernal at Ineos as well (pre crash, but with his back problems) He then disappeared after the spring 22, only showing up for Algarve twice. Now he's finally back... and is he worse than somebody like Adam Yates? Who last year, after years of not managing to bring the perfomances of his 1 week tours to a GT finally did it. Is this Martinez really weaker than Adam Yates? Or Simon Yates for that matter?
O'Connor, Gall, are we sure Gall is actually better than O'Connor? 8th at the Tour last year, nice, O'Connor was 4th in 21.. last year Gall was better yes, but it's not like they all are the same every year. Had Gall started here he would have started as favorite for the third podium spot like O'Connor did. With the re-emergence of Martinez then he would be number 4.
Arensman looks to repeat his Giro of last year, not much development there, TT stronger, rest a bit shaky.
Tiberi young and new at this high GT level, but certainly doesn't look bad. On the contrary, together with Piganzoli and Pellizarri looks like Italy has already found the solution to its lack of GC riders.
Of course the field is not very strong, ok, weak, but it's more of a depth problem than the level of the ones behind Pogacar. Would have been nice to see Landa or Hindley or Bilbao or Carlos Rodriguez, but well, except for Quick those teams have leaders that fight for the top 5....... Or Simon Yates or whoever. But Vingegaard put 10' into third place at the Tour last year. Only Pogacar is at a similar level, so let's not pretend Pogacar wouldn't have put a similar amount of time into Mas, Gaudu, Landa, Simon Yates, Gall, Carlos Rodriguez, Carapaz etc. Roglic would be closer, most likely. Hopefully in 2026 or so we'll see both Pogacar and Vingegaard attempt the Giro-Tour double.
