pietersen can bowl and morgan is a great fielder
collingwood has dropped a few in this series
Morgan has scored runs in every match he has played but hasnt got to play many tests cos he isnt getting a chance.
I feel that Morgan should have at least got a chance
ye but a spinner isn't always appropriate as a fill in bowler, Colly usually gets decent economy for his spells.
and ye Morgan is a great fielder, but Colly is world class, and i don't think i remember him "dropping" much, maybe not holding onto a great catch or two, but with the positions he is asked to field means he will end up having a lot of the ball at him.
Morgan has scored runs against teams not of Australia's standing, he's played 6 tests, and got 1 century which is great, no 50's and an average of 32. He will soon take over from Colly with his age thats for sure, but i don't think Colly deserves to go just yet.
against teams like the Aussies Colly has that ability to be effective and significant with his contribution, Morgan no one knows, so at present i see it as a no brainer.
although dont get me wrong Morgan is quality, think he's great, his time will come! probably for the next Ashes.
