He'll improve but durability is certainly an issue, I think he could be a sneaky good forward but he's totally unproven and his scoring has been pure clearance work previously, detests a cheap touch.
Basically it would be pretty shocking if he suddenly became a keeper this year after last year and having never done it through his prime before the back injury which means he's a cash cow that doesn't make enough cash. At least Taranto, Daicos, Prestia or even Sloane and Yeo in his rough price bracket either have youth or premium scoring histories behind them.
Ultimately I just think you're better spending 450k range money on a back or forward if you're punting in that price range. I think Wingard, Greene, De Goey, Heeney et al are far more likely to hit premium numbers simply because the threshold is 10-15 points lower. Backs not quite as much but Houli, Williams, Witherden, McEvoy, Duggan et al at east have cases and the threshold is still 5-15 points lower as well. Getting to the 105+ range of being an M8 and realistically 110+ for a good M8 is just such a big leap compared to getting to 95-100 range for F/D6. Obviously if you have different reads on the positions that changes things.
