Gaff is a much better player than Conca. Runs straight lines, hard, skilled and fast. Everything that Conca isn't. Doubt they would give him to us.
Different players entirely. Like replacing Foley with Grigg. If we lose Conca then Gaff will not be a replacement, he will be an addition. We will still need to replace Conca.
The Heppell miss is looking like a bigger blunder every day.
How? Heppell and Conca play different roles and I haven't seen anything in Heppell to suggest he will be a better player over his career than Conca.
