White is filling in in areas at the moment that we are not ready to fill with other options or those options aren't yet ready. He is also useful to ride shotgun whilst we are blooding the younger, newer guys. He at least puts in, albeit without being super talented, and making some mistakes at times - something you could also say about some of our other players. No he is probably not part of our longer term future but rather he is a stop gap. To call him a complete waste of time is pretty harsh IMO.
Reality always wins in the end.
