I took this quote from another thread, because I what to hear the opinions from others about Endo possible promotion to makuuchi... I personally thinks that even with a 14-1 yusho he will not be promoted directly to makuuchi.
In january Takanoiwa took the juryo-yusho as J13e with a 13-2 and was "only" promoted to J4w. And today Endo has an even lower rank as J13w.
And, as far as I can use the query correctly, the lowest position for an "instant" makuuchi promotion with 14-1Y was J11w.
Sagatsukasa 2011.05 J12e 13-2 Y 2011.07 M13e 8-7 With J12e and 13:2 Yusho he was promotted, Endo with 14:1 has good chances because in my opinion it will be more makuuchi slots that it is actually juryo rikishi to fill that.
