As great as Okada's run as champ has been in terms of quality matches, it hasn't been the most drama filled run for sure. I guess they kind of painted themselves in the corner, either Okada only has matches with guys at the very tippy top and becomes a Brock like character who's never around or he wrestles more frequently and has more matches with guys who don't have a real chance of winning.
If nothing else it makes the other guy look good having a top quality match with the champ, even in a losing effort. One thing the booking tends to be good at for them is the whole "make guys look good while losing" deal, which didn't used to be difficult but is a lost art these days.
