Look lads, Howard is just one of those keepers. After a largely consistent first few years for us, in recent memory he's been on somewhat of a roller-coaster - crap in 12/13, boss in 13/14, crap in 14/15. Hopefully he'll be back to boss this season, but it's to early to tell despite a decent enough start to the season.
Could we get better? Yes.
However, the money a decent replacement would set us back could be better spent on more priority positions such as a creative player to break down stubborn defences and decent cover at RB and even another back up striker could still be required next summer given Kone's age and the fact that Rodriguez is a gamble albeit at a nominal fee.
But even then there are two things you cannot underestimate, experience and value to the dressing room. The latter of those two points is one that seems to be very important with regards to the current group of players. The manager appreciates this, you have every right to disagree of course but it's a recurring point in many of his interviews so I'm willing to accept it has some importance.
Howard is doing fine thus far, though. The manager has always placed his absolute trust in him so hopefully he can put last season behind him.
