He was (I think) a Platinum until age 50 with Ganassi then turned 56 in March this year which drops him to a Silver, however
• has been a Factory Driver, paid by a car manufacturer, with results to match;
This makes him at least a Gold unless he can show he is bringing money to the team and not cashing checks from Toyota. This also applies to Legge, Segal, and Negri in the Acura. Negri slipped in as a Silver because he is 52 but if he is cashing checks he should automatically be a Gold at minimum.
Either way this path that IMSA is taking which is basically pushing the Am drivers out of the series while stacking the deck with fake Silver drivers is a road to a dead class. Guys like Ben Keating who have day jobs and spend huge amounts of money in the series will grow tired of hot shoe former Porsche cup drivers and ex open wheel drivers who are on the fringe of whatever series they ran in but cant get a seat at Penske or Mercedes and leave the series for PWC or ELMS.
IMSA might have a dream that they can be a All-Pro sportscar series with the best drivers in the world but the series is built on a sink hole. The product is unwatchable on TV for one which makes it impossible to market unless you like watching a 2.5 hr infomercial with some noises in the background. Until that very basic thing is fixed they are pissing in the wind. OEM's will not stick around when the ROI is so small when the TV numbers are 150,000 avg viewers for a race.
GTLM can still be the top GT class with the link to Le Mans but they need to split the GTD class into GTD-Pro and GTD-Am. Doing that will allow the factory backed cars who are there to sell GT3 cars a place to show how great their BOP skills are and the guys like Keating who are writing the checks and are really capable will have a place to play too. The path they are on now will lead to them having neither one in 2018 when the factories move on and the Am's are in another series.
