Difference with Dan for me is that when he wins the ball you can be confident he can hold it up and keep possession - The difference last night with him in midfield compared to Airdrie was night and day.
I'll be disappointed if he goes and probably more so if its to another SPFL club.
Smith coming in could be a good option for midfield but given Kane/Clark's fitness issues, May's age and DJ and Benjis lack of experience I'd prioritise a striker over another midfielder.
