Those innings came at 3, a position he's clearly not suited to. His record down the order is very good, and far better than his record at 3, so I'd like to see him given more than 1 Test batting at 6 before he's binned again. He did score important runs in the Ashes as well, especially at The Oval. It's Trott that took the plaudits for his 2nd innings hundred, but without Bell's 72 in the 1st innings, England wouldn't have been in such a good position going into that 2nd innings.
There's no proof that Wright's actually got similar to mental strength to Collingwood either, for all we know, he could have the same mental inferiorities when it comes to Test cricket as Bell, and with that a far worse technique. Wright's done nothing in his time in International cricket to prove he's of international standard with the bat, and calling him into the Test side would be a step backwards for me, even in comparison with Bell.
