Reason I liked the Wheeler signing over the Arrieta signing is the price was right, if he never is more than a 2/3 giving you 3 WAR a year it's still a decent signing, but Wheeler had upside left, whereas Arrieta was already losing velocity before we signed him, at best he'd justify the cost, but there was only downside risk. Never pay for past production.
Worrisome thing about Neris' inning, his velocity is down 2 MPH from his "norm," hopefully that's just early season, though his splitter was working. If the splitter is on and he can throw it for strikes, location is more important than velocity for his FB, but still . . .
