You severely underestimate how poor our midfield was this season outside of Devoy and Clarke, both of whom could have won player of the season having only played half a season.
Flores can kick a lovely ball. Outside of that he's pretty poor. Levingston has patches of decent play but is poor overall
Doherty played as a defender this year
Coote never got near the heights of last year and didn't even make the squad on a couple of different occasions
McManus has potential but still very young and prone to a rookie error
There were probably others who never saw the pitch or spent more time injured than playing so I didn't bother including them.
If McDonnell can be consistently available and put in 6/10 performances week in week out that's a big improvement on the current lot.
