For me, I think Luke is coming way too deep. His greatest strength is arriving in the 6 yard box at the right time to score tap-ins. Look at how many of his goals were like that in the first half of last season, it was staggering. Now, he's coming too deep and trying to set up Hardie with through balls. We all know that Hardie's strength is his pace and dribbling ability, so it makes sense for Luke to turn provider, but it means he won't score anywhere near as many as he's simply not in the right positions. He can't do both, and I feel for Luke, but I don't think he's suited to RL's style of play this season.
As for Agard, I haven't seen enough of him to really warrant him starting yet. He was pretty ineffective against Wigan when he came on so maybe we'd be better off freeing up his wages in January, especially with Ennis due back (hopefully) soon.
