I'm not disputing they weren't good at Falkirk, you're opinion on them is tainted by that experience. White is improving all the time, he's a different players from the one you had at Falkirk.
O'Brien was a good young player at Livi, when he came back his experience was needed to keep us up, he's on his last legs at this level though, hasn't the stamina to play a full season week after week.
Sounds like Ollie could go either way, some Falkirk fans rate him, some don't, seems he had off field problems that messed him up when he was at Falkirk, so maybe he's ready to give it a go again.
