I don't think it will make much difference.
If Newman scores badly tonight,the same Poole fan's that are slagging him of for riding tonight,will be saying"Newman will be back where he belongs in 2018 on a 4.something.
I think the form of David Bellego is a worry for Swindon tonight.Apart from if they know something we don't..He scored 13 the last time he rode Poole.His form has nose dived lately.
I don't think Newman for BWD (who scored 8+2 from 4 yesterday,won't make much difference tbh.
For me Bellego could be the key tonight.
