Yep, supposedly any Brit player in the top 250 will get a Wimbledon main draw WC...so these should fall to Boggo, Goodall and Ward. Depending on the date of the cut-off, Ward might finish a couple of places outside the top 250 (especially if he loses the Sarasota final to Ball), but he should still be rewarded for his recent form/results imo. Boggo and Goodall are pretty lucky tbh...they are both set to fall outside the top 250 within the next 3-4 months, and the former is probably in his worst form for some 4-5 years. If he couldn't do anything with a main draw WC over the last handful of years (and he had a couple of legitimate opportunities - Kim and Guccione spring to mind), I highly doubt he will now.
Evans probably won't make the top 250 in time, but maybe he should be given a chance, if only because he won one of our domestic challengers a couple of months ago. But even then, I'm not sure he is currently a strong enough player for the rigours of the challenger tour, yet alone ATP action.
Again, maybe you could argue that Eaton should get one, having been the only male Brit (forgetting Murray) to win a round at Wimbledon last year (and having to qualify), and also sparing us extreme embarrassment in March's Davis Cup tie. Obviously he is well suited to grass, but really he has done practically nothing in the last 12 months, so it is hard to reward that. Reminds me a little of Flanagan...living on an over-inflated ranking for one year, before tumbling back down to his real level. If you hand him a WC, why not open the floodgates and extend the same courtesy to Bloomfield and Marray, who would also enjoy playing on grass?
And then there are the foreign players...Dent, Grosjean, Nishikori, Dimitrov etc.
