I hope Taguchi wins BOSJ. Not only has he had a good run for this tournament, but him winning the BOSJ would help keep him as a strongly booked member of the junior heavyweight division with his experience, you could set up a Kushida feud, a BUSHI feud, and just have more of a veteran type role like Kanemoto used to server and Liger serves but without all the age and using a wrestler that's relatively over in Taguchi. I used the words 'stepping stone' and that's all an Ospready win would serve. Likely lead to one IWGP Jr title reign, maybe a month or two of forgettable feuds that don't build the division as the premiere place to be because there is ABSOLUTEY no way Ospreay isn't in the Heavyweight division by 2017. Maybe even by the end of the year. Ospreay doesn't need the win if he's going to get the push regardless.
Ideally though, I would have liked BUSHI to finally get his chance. I think a KUSHIDA/BUSHI feud is extremely natural and helps the division rather than just something to bump Ospreay's worth up or something to solidify Taguchi with.
I would have also liekd Kamaitachi in BOSJ to win it, but the way NJPW's booking is? There's absolutely no way they don't have bigger plans for Kamaitachi. They'd be foolish not to look at the big picture with someone as ridiculously talented and capable of all styles like him. Which continues to suck for the junior division. At this point, I can only hope they close NOAH and pick up their juniors, merge them with NJPW's juniors, and have a proper division going.
