The successful TPs (or team managers in olden days) don't have graduate education. In reverse order the WCC TPs are - F3000 driver (Horner won a single point in 2 years), Rindt's spanner man (Dennis), atomic instrument apprentice (Brawn), ski instructor/bankrupt restaurateur/door-to-door insurance salesman/convicted fraudster/fugitive (Briatore), travelling grocery salesman (Williams), timber merchant (Tyrell), RAAF flight mechanic (Brabham), cosmetics factory manager (Dragoni) , bearings factory manager (Vandervell) and race mechanic (Cooper).
The exceptions are Ferrari who won all their WCC titles since 1974 with 3 business school graduates; Lotus who were led by a structural engineer graduate from UCL in London; and BRM led by Raymond Mays (Engineering at Christ College Cambridge).
So the lesson from history is that one should avoid graduates running a F1 team unless the car is red (or white and blue in North America). Merc swapping an apprentice for someone with even less higher education seems to be a good move.
Alas the runes are against Whitmarsh.
