What stat do you prefer? I personally like HR/FB ratio. Colvin's is completely unsustainable unless he's on par with the Adam Dunns and Albert Pujols' of the world. Combine that with one of the worst zone recognitions in the league and I think there's a very high likely hood of regression. Colvin's HR/FB will probably go down. If he played 10 years, he probably would have a couple that were up that high but most will be lower. He also does need to improve his BB/K ratio. His BB ratio is poor but not absurdly poor (Corey Hart, Aramis Ramirez, Carl Crawford, Adrian Beltre are just some examples of guys who have survived with worse BB ratios in their careers than Colvin has had). The strikeouts have to come down though. His strikeouts were better after the All-Star break than before. If he can continue to lower that into the 23-25 percent range which would be more in range with his minor league numbers than he can be successful even when his home runs/FB drop. It's not absurd to put Colvin in as a starter. He's not a great choice for starter because he's probably going to be around league average with more chance of a downside than upside. But it's not like corner OF has been that big of a premium offensive position lately. If he did put up an .800+ OPS, that would be just fine at any of the OF spots even as a starter and even with a relatively low OBP. It would be a position the Cubs would have to upgrade if he didn't get any better as he got expensive but to get cheap league average production is fine for one spot.
