You state they were **** deals as if it is a factual statement, but it is only your opinion. My opinion is that we sold Tomlin for as much as we could and replaced him with Downing (and also Ramirez in January). We got promoted the following season while Tomlin played for 6 clubs in the following 4 seasons and was not a success at any of them. I'd say the balance of the evidence points to that being a shrewd bit of business but who knows what might have happened if we had kept Tomlin.
It is also my opinion that the money we got for Chuba and Tav was the best we could hope for and therefore not ****.
Ok but that's a somewhat different argument IMO. If we had kept Chuba and if he scored the goals to get us promoted, the decision would have been a good one. However, there was no guarantee that he could repeat last season and if he signed a pre-contract elsewhere in January, he might have been less motivated to perform for us as a result. Ultimately the club felt that the money on the table could be better utilised building for the future, rather than being gambled on an all or nothing season. Same with Tav.
We could have kept both and gambled on promotion, but it is far from certain that we would have gone up had we kept either. What can't be disputed though is that we cashed in at market value.
