The Rams made solid picks, but Sam Bradford sucks. If the DT from Pitt is as good as the hype, they will have an incredible DL, on par with anyone in the league. Try and trade Bradford for anything, eat the money and cut him. You aren't winning in the playoffs with him at QB. He's not so bad that it's impossible to sneak in at 9-7 or 10-6, but I would have no belief he could take you past the wild card round.
Word is Robinson is going to play LG or RT. He could end up a good player, but he has very little experience pass blocking. An OL isn't making them a good team. A good QB would.
