Vecchi would probably end up as Strama version 2. .
At this stage the question should be if this could be actually worse than still seeing mazzari at inter.
to me vecchi would be a good choice, not only because he already has experience with pro football (even if it was only serie b), but also because he already showed theorical knowledge by getting the coaching license with stand out results (100 of 100 points).
if i remember correctly strama failed in his first exam and got the license in the second.
besides, vecchi would know how he should or if he should use some of the youth players from a primavera that is as dominating as it comes.
also, with a bit of luck injury wise, i think that it would not be so bad to have "Strama 2.0" as we could at least snap up a winning streak that is higher than 2 games.
adding that he would be very cheap comparing to other options, it wouldnt be quite the worst idea to give this guy a chance.
at this point id rather have a player coach than mazzari, so my oppinion might be a bit of biased, but i dont think that vecchi could do as bad as mazzarri when it comes to game plan; he could fail, but there is potential that he might succeed, whereas i dont see this potential in mazzarri
