Bodin is on a one year contract and adds depth to the club. Worst case scenario he doesn't get much of a run and leaves at the end of the season. Not sure what benefit we have from getting rid at this stage?
Likewise with McNally. Atkinson looked shaky as anything when he started (red card against Lincoln last year, albeit rescinded) and a few occasions where he got caught badly out of position. Bear in mind he'd played a lot more men's football by that stage of his career. Also going down to having Mous as our only real backup for a position strikes me as, to put it politely, more than a little risky.
