He needs to play, and play a lot, so he needs to go on loan, he won't get game time here in a promotion chasing side. Game time in a non promotion side is kind of pointless, I'd rather roll the dice.
I don't think he's good enough for a promotion side yet, so even if we did end up light on forwards or not near chasing promotion then having him playing won't solve that.
If it gives us a better chance of getting a potentially better striker then I'm all for it, but I'm not sure we 100% need it. This is assuming LL stays, we have Conway, Forss who are better players than Coburn, and Burgzorg would probably score more than Coburn if up front.
I'm not saying Coburn won't make it though, far from that, but we don't have the time to give him the games he needs, if we want promotion.
