I agree on the sub rule. There are generally 2 concerns most have with Lloyd. 1 - Doesn't get involved enough and 2 - Defensive pressure.
I think the first is a bit of a fallacy due to the number of times he has been sub. I had a quick look at his stats for the last 2 years and pro-rated them to an 85% TOG % (in the 5 games he played the full game last year he averaged 88% and had 87% on Thursday).
In terms of disposal he would have averaged 13.2 in 2014 and 16.2 last year. He got 14 on Thursday. I think thats perfectly fine for the role that he plays. For comparison, Ballantyne averages 13, Jeff Garlett 11, Betts 12 (last 2 years 13-14), so he gets involved enough.
His goals have not been bad either, again pro-rata up he averaged 1.2 goals per game in 2014, 1.6 last year which is again right up there for me.
The area that he struggles is tackling, last year he went backwards (actually would have averaged 3.6 in 2014) to only 2.6 which is well below those other guys. He had 3 on Thursday so if he can keep that up then he can certainly be a big weapon for us this year and could certainly score 30-35 if he plays all year for us.
