Schumacher is still worthy of a GP drive if he is fit enough and wants to. I certainly think he would be capable of points scoring finishes. I just dont see him being anywhere near the pace of a Lewis Hamilton in the same car. My point being, Schumacher never seemed to be a driver happy to make up the numbers, but if he returned, I think he would be doing just that. Despite that, I hope he does return but I think it will be more Alan Jones than Niki Lauda. The driver field today has a lot more quality than the mid to late 1990's when Schumacher was up against Hill, Coulthard, Barrichello, Irvine, an old Berger, Villeneuve, Hakkinen, Ralf etc.
With regards to the slightly off topic comments that I seemed to have triggered, i'll wrap up with the following:
In MY opinion (as we merely seem to be going in circles) I believe in the following:
For a period, Schumacher was probably the best overall driver in F1. Perhaps Hakkinen was his only match before the new generation came in. The rest of the field in those days was pretty poor quality.
Schumacher has had pretty medicore teammates throughout his career. An old Patrese, Brundle, Verstappen, Lehto, Irvine and Barrichello....that is low quality stuff when you consider what Lewis dealt with from day 1.
Schumacher also has always had an obsurd amount of preferential treatment when at Ferrari and Benetton.
Schumacher made an increasing number of silly mistakes towards the latter part of his career
Schumacher looked a bit past it at times when up against Alonso.
Lewis Hamilton is more talented than Schumacher was at his peak.
Lewis Hamilton beat a current double world champion in equal cars in his first season of F1.
Lewis Hamilton is more of a known quantity than Schumacher was because he raced against the previous best in F1 (Alonso) in the same team and beat him.
Lewis Hamilton in his rookie season beat Fernando Alonso over a season when Alonso was considered the best of the lot.
Schumacher is capable of doing a decent job if he does return to F1 and can score points and perhaps podiums in the right situation.
Schumacher had to beat the likes of Hill and Villeneuve then. But now he would be dealling with something completley different. A younger, fitter, and I think one of the fastest drivers ever to grace GP racing, Lewis Hamilton. I dont think Schumacher would have dealt with him at his peak, and there is certainly no way in hell he could get anywhere near Lewis hamilton at the age of 40!
I hope Schumacher does return. I just dont know why he would be happy to make up the numbers and why he doesnt try something new and challenege himself in a more refreshing way.
