Yeah he has. I hope he returns to SA TBH, though don't know if he has any plans to do such. You hope Gerald Majola might have had a word with him though, as he reportedly was McLaren and someone else.
Dunno why on Earth Essex signed Maunders at all, he's patently not a county-standard batsman. Annoys the heck out of me when counties sign such players - such a waste of money. Maunders would be much better-served getting another job.
As for Matthew Walker, well, he's been pushed out of the Kent team by all the Kolpaks (like Dexter, as well as van Jaarsveld, Kemp and McLaren). Same was true of Ed Smith. Always a shame to see Kent-developed batsmen leave the club and go elsewhere. If they still had both and less Kolpaks their batting unit (Denly, Key, Smith, Walker, Stevens) would be almost all Kent-developed. Bet they also wish they'd got rid of Geraint Jones rather than O'Brien too, as the latter now appears to be the better batsman.
Walker can't be that young any more either.
