TBH I would bite the bullet and play Tevaga at lock.. He offers something different, but might be more beneficial coming off the bench for the last 50 minutes against tired forwards. I think Harris has to play second row because he is easily our best in the position.
Papalii goes better in the middle than out wide. I'd probably go;
JTB
Egan
Blair
Katoa
Harris
Tevaga/Papalii
Lawton
Hetherington
Paasi
Tevaga/Papalii/Murchie
Will be interesting to see who will replace Paasi, he hasn't offered much this season. I would prefer we sign a guy for the final half of the comp who is off contract next season, rather than a loan player. Maybe a Peni Terepo, John Asiata, Josh Kerr.. But doubt those clubs would let a player of that sort of caliber just walk.
