I don't think it is worth agonising over Danns and Beckford. They were not significant enough players, Beckford arguably has been woeful most of time. But even if we argue over that point, better replacements are in the team and on the bench.
Incidentally in terms of whether 'personal' factors have come into Pearson's decision to drop or move any players... has anybody stopped to consider if sometimes these can be legitimate reasons for for doing so? 'Personal reasons' isn't always blind prejudice or bullying (those are obviously unacceptable personal reasons). Players who ar bad influences in the dressing room or bad influences off the field can be very bad for a team. If someone undermines the manager in the dressing room during team talks, or doesn't listen to advice or instructions, or if someone is out boozing and gambling too much or doing drugs off the field - these are legitimate reasons to drop a player and depending on the extent of these issues, to move them out as quickly as possible.
We don't know what personal issues Pearson has with these two players (if any) but even if none of the above factors are present, I think on performance terms and value for money, there are very sound reasons for getting rid of those two. Hazzman has given an excellent view on how Danns is a player who is not as good as some people think he is, whilst with Beckford it is even easier to make this case in my opinion. In my view the return on investment for Beckford has not been good enough. If I were manager any player who took a big slice of my transfer budget and a very big slice of my wages budget would have to be performing as one of the best players week in week out. Beckford has been one of the worst performing players week in week out with the odd good game here and there. That's not good enough; the return on investment has not been in evidence. Beckford will have to ply his trade elsewhere.
Moreover if any of the 'personal reasons' mentioned above are at play, they have to go. But the case for moving them on in playing terms alone seems well justified in my view.
