I agree that Baumann's squad planning is by far a bigger culprit for our situation, but I also think that while pretty poor and lacking in several positions, the squad is still good enough NOT to be fighting against relegation for two years in a row. Yes, you can't blame Kohfeldt for Sargent's lack of finishing or Eggestein's misplaced passes etc., but what I do fail to see is any recognisable philosophy and strategy on the pitch; there doesn't seem to be any ideas and match plan at all - all I've seen in our recent matches is just long balls being hoofed forward mindlessly - and this is surely responsibility of the head coach? Just as he's responsible for choosing to continue with the 5 at the back although is clearly not working, or with playing Sargent as #10, or generally allowing underperforming players to remain in the starting XI every matchday. I actually think Kohfeldt is not a bad manager who would likely do well with a squad of higher quality, but in our current situation he's just not pulling it off. Also looking forward, if we do manage to stay up again, after all, what will change? Likely, nothing at all. With no financial resources and no players in the club to sell for a substantial transfer fee, I can't see us strengthening the squad during the summer, so it's likely that next season the quality of the players at Kohfeldt's disposal will be more or less the same, so it's probably just delaying the inevitable.
That said, I can absolutely understand the board allowing him to continue. First of all, there's hardly any alternative on the market that we could afford (while paying Kohfeldt too), and with 3 matchdays left, it's impossible to say if that would even make any difference. Could have been worth a try though.
