Exactly Champers. There will be times when plan A isn't working and we have to have a plan b, plan c or even a plan d to win the game. For me, out usual tactics are plan a, more width and use of wingers is plan b, plan c is sticking a few big uns in the box and chucking the ball in there with 15 to go, and plan d is we just shoot the opposition bstards if we need to. CW will have it all sorted.
But I digress. Hanson is a very arkward player to play against and is physically imtimidating to opposition centre halves. Why wouldn't you want a relatively cheap option like him to come off the bench and 'cause some bollox' if that is what the occasion merits at that time? It's been done for many a year, Bassett had Whitehurst for this job, Warnock had the Chief. The other mediocre managers we have had recently probably didn't have a dedicated big lad to come off the bench or a plan b, but then they didn't have a plan full stop either. Hanson can be our Chief this season and he was worth his weight in gold that lad.
