Arrows and Jaguar were passable? I don't think so, and PDLR scored points in them. Hell, he ran 3rd for almost half of Austria 2000 before yet another mechanical DNF. If you mean 2006, well if he was as bad as you imply why didn't McLaren run Hamilton early?
If you mean Karthikeyan, then I've been banging on about that in this thread for some time.
Valsecchi I believe is tied to a Lotus contract, I don't know what Jaime's long term plans are though. Seems to be DJ'ing right now
I've been clear about PdlR having had reasonable pace in his youth, but even before arriving at Sauber in 2010, it had deserted him.
McLaren not running Hamilton early was clear from what they said and what they did: they wanted to protect him and give him a proper pre-season and induction, and refused point blank to risk it -- if you dust off some old Autosports, you'll notice Hamilton was already faster at test sessions.
de la Rosa was a solid reasonable-to-okay in his youth. He's now 41 and while Schumacher has gone from exceptional to good, PdlR was barely if ever truly good.
ETA: Just to note, I got bored going through stats, but I invite you to find an occassion in 2006 when he was with 0.6 seconds of Raikkonen.
