Which way will the ICL returnees go? My guess is that Ablish will be picked up quickly by Kings XI Punjab (a.k.a. Arsenal), as they could do with an upgrade in their domestic bowling base. Their best bowler, after Irfan, is T20 misfit Sreesanth, and the scratchy VRV Singh and not-so-impressive Vik Malik. The only real downside is that he's not much of a batsman.
Monish Mishra is another hot target, and may be snared quickly by one of Delhi and Punjab. Delhi have a soft spot in their middle order, which they may have to fortify- they struggled with Manoj Tiwary and Mithun Manhas in the past. Punjab, on the other hand, lack strikers, and could use one with his strike rate. All of that, however, is banking on impressive stats on just four mainstream matches, apart form how many he got with ICL.
The most obvious destination for Vignesh would be Chennai, but though his ICL stats are amazing, he's not so hot in mainstream T20- but that was a long time ago, and things may change. Deccan may need a local all-rounder, so they may chase him, as also Mumbai and Punjab.
Abid Nabi may be a player of interest for some. He's primarily a bowler, once tipped as a speedster, but he's also been useful as a striker lower down- the only problem being his T20 bowling average over 49. Then again, T20 stats may be taken with a pinch of salt by some, who may need a run-scoring bowler, who can also field well. Rajasthan may chase him.
Abbas Ali is primarily a batsman, and his strike rate isn't too impressive, but he can hang around for some time. His bowling, however, has come good in T20, as he's picked up wickets regularly, for not too many. He's a left-handed batsman and left-arm spinner, who may come useful for one of Hyderabad or Mumbai.
