I haven't agreed with it either. I perhaps may have been waiting to see how he goes when the racing starts or he has a season under his belt (let alone 2 world championships) to make any evaluation of him at all, let alone his mental toughness, given he is a rookie and this is only testing, in which mental toughness if it does have any influence in general is presumably less important, unless you want to call Casey Stoner incredibly mentally tough, since he still excels at testing not having raced for 4 seasons.
Much the same Mike, and as I have said previously, for every rookie I believe that they should all receive guaranteed 2 year contracts as year 1 should be no more than a learning year with year 2 when we expect improved results.
Whilst this discussion has drawn to Rins, I personally am also keeping an eye on Zarco and Folger who have performed extremely well in testing thus far as to me, they will be a good marker for the likes of Rins, but also for me the likes of Miller who should (IMO) be more highly competitive as he is fit and on an updated Honda.
Whilst I suspect the battle up top will be fought hard and somewhat publically (it having already started with Vinales calling out Marquez for following) I suspect that the rookie battle may well be the better battle as (with no disrespect to Tito here), this year we have a number of new riders to the field, together with older returns (Abrahams).
Testing is just testing and it has been good to see the numbers of laps ridden by some of these riders (Miller for example has ridden 90 or so each day at the island with no gravel trap visits) whilst it is said that Folger and Zarco also did large numbers of laps (not seen Rins output).
I actually look forward to this year as whilst I suspect that the usual suspects will be at play, I also reckon we will see a few upsets of the applecarts throughout the year .......... well, that is the hope anyway
