Surely a striker would make sense
Roofe has been great so far, not only in goals scored, but for staying pretty much injury free,& doesn't pick up too many cards etc, if the worst should happen, and he misses say 6-7 games, that's a massive chunk of firepower gone -
Roberts still really getting up to speed / hardly prolific in goal stakes , Bamford sadly who knows when & where, Harrisons been tried as CF, but again mediocre, that leaves only Edmondson, possibly Clarke.
This is the clubs last chance to bring in suitable back-up - the chasing clubs, Norwich / WBA / Boro / Derby, all seem to have better striker options, which just might make the difference come May
