they’re different styles. while Conti is the short kicking, long pass, clutch play whiz, Isdale is the more methodical, controlling type who has a good running and long kicking game.
it comes down to personal preference of course, but for mine Conti has the more well rounded game and possesses the skillset already, whereas Isdale would be the other way round.
I say this knowing that Isdale has only played one year of Matts, and there’s every chance that in his second year he improves on his showing. I think he’s a good prospect in his own right, I just rate Conti higher.
