I agree it sounds like lag or clock issue.

I don't do the last second thing (well not with BvB anyway) My strategy is to bid right away to intimidate the other bidders..Often it works.

I also don't bother the first few days of the Season since BvB's TL is hyper competitive.. I expect this Season is different due to the server changes they are making, but on some of my teams on other servers I got guys for 1T so obviously some levels/servers are more competitive than others.
