Peni being a first grade regular all of last year (while Jane Evans spent the season getting "fit" playing for Wenty) and being named in the 21 man squad this week despite his misdemeanour and time served, tells you everything you need to know about Terepo's standing in the squad. Evans won't be anywhere near first grade once Ma'u, Brown and Peni all get their groove back...Evans and Peni is about the comparison. Evans made 97m off the bench last week. Peni sat at home and drank bourbon out of a coffee cup or whatever.
So no, Peni doesn't necessarily come straight back in
I'm not a Peni apologist or fan boy (although I would say he was our best player in 2018), but if he stays injury free and out of trouble he will be picked ahead of Evans, Gower and yes, possibly Mannah, long term whilst BA is still coach.
